Role of Supplemental Breast MRI in Screening Women with Mammographically Dense Breasts: A Systematic Review and Meta-analysis.

BACKGROUND: High mammographic density increases breast cancer risk and reduces mammographic sensitivity. We reviewed evidence on accuracy of supplemental MRI for women with dense breasts at average or increased risk. METHODS: PubMed and Embase were searched 1995-2022. Articles were included if women received breast MRI following 2D or tomosynthesis mammography. Risk of bias was assessed using QUADAS-2. Analysis used independent studies from the articles. Fixed-effect meta-analytic summaries were estimated for predefined groups (PROSPERO: 230277). RESULTS: Eighteen primary research articles (24 studies) were identified in women aged 19-87 years. Breast density was heterogeneously or extremely dense (BI-RADS C/D) in 15/18 articles and extremely dense (BI-RADS D) in 3/18 articles. Twelve of 18 articles reported on increased-risk populations. Following 21 440 negative mammographic examinations, 288/320 cancers were detected by MRI. Substantial variation was observed between studies in MRI cancer detection rate, partly associated with prevalent vs incident MRI exams (prevalent: 16.6/1000 exams, 12 studies; incident: 6.8/1000 exams, 7 studies). MRI had high sensitivity for mammographically occult cancer (20 studies with at least 1-year follow-up). In 5/18 articles with sufficient data to estimate relative MRI detection rate, approximately 2 in 3 cancers were detected by MRI (66.3%, 95% CI, 56.3%-75.5%) but not mammography. Positive predictive value was higher for more recent studies. Risk of bias was low in most studies. CONCLUSION: Supplemental breast MRI following negative mammography in women with dense breasts has breast cancer detection rates of ~16.6/1000 at prevalent and ~6.8/1000 at incident MRI exams, considering both high and average risk settings.

Effect of Leflunomide-Metal Complexes on ROS, TNF, and Brain Indolamines in Comparison with Anti-Depressants as Adjunct Therapy in Rheumatoid Arthritic Model.

Leflunomide is an isoxazole immunomodulating drug used to treat rheumatoid arthritis (RA). It is adopted as a metal-containing molecule to proceed with saturated salts of essential and detected metals; it amends the pharmacokinetic and pharmacodynamics activity of leflunomide to provide [M(Lef)4]X2-type complexes. Earlier it has been reported that after forming complexes with metals, leflunomide anti-arthritic activity was significantly altered in an acute arthritic model. In the present study, we evaluated the possible modification in anti-arthritic activities of leflunomide-metal complexes (Mg+2, Ca+2, Fe+2, Zn+2) with and without an anti-depressant drug, i.e., fluoxetine (10 mg/kg) in a chronic AIA model. Rats (n = 5) were administered with 0.1 mL of CFA into the right hind paw while treated groups received leflunomide and its metal complexes orally (3.2 mg/kg) for 24 days. On the final day of experiment, rats were sacrificed; a specific rat immunoassay ELISA kit was used to assess TNF-α in serum samples and read at 450 nm; a tissue sample of a paw was homogenized in a phosphate buffer using DCFH-DA dye for binding to assess ROS. A rat's brain sample was homogenized and evaluated for tryptophan, serotonin (5-HT), and HIAA by RP-HPLC with EC detector. The overall TNF production was altered in treated rats. In addition, a decreased ROS was observed in all categories, except lef+Mg+2 group. Moreover, depletion in the brain indolamine levels were found in treated groups; an upraised level of these indolamines was observed when fluoxetine was added. It is concluded that metals affect leflunomide activity on complexation and simultaneous administration of fluoxetine cope up with the depression in arthritic-induced rats.

Molecular marker identification, antioxidant, antinociceptive, and anti-inflammatory responsiveness of malonic acid capped silver nanoparticle.

Nano-sized silver has drawn a great deal of attention in the field of health sciences owing to its remarkable therapeutic applications. Interestingly, the method applied to synthesize nanoparticles and the choice of reagents considerably influence their therapeutic potential and toxicities. Current research has explored the toxicity, anti-inflammatory, antinociceptive, and antioxidant responses of the malonic acid-capped silver nanoparticles (MA-AgNPs (C) by using sodium borohydride as a reducing agent at low temperatures by employing both in vitro and in vivo approaches. Furthermore, it has highlighted the synergistic effect of these novel compounds with conventional anti-inflammatory therapeutic agents. Acute and sub-acute toxicity analysis performed following OECD guidelines showed that the studied MA-AgNPs (C) are safer, and prominent toxic signs have not been detected at the highest studied dose of 2,000 mg/kg. Cytotoxicity evaluation through brine shrimp lethality revealed 20% lethality at the highest concentration of 169.8 µg/mL. Significantly, positive anti-inflammatory and analgesic responses alone as well as synergism with the standard were identified through in vitro as well as in vivo methods which were more potent at a lower dose (200 mg/kg). Notably synergistic outcomes were more pronounced than individual ones, indicating their prominent effect as a feasible drug delivery system. IL-6 and TNF-α assessment in excised paw tissue through RTPCR technique further supported their anti-inflammatory potential. DPPH assay revealed eminent in vitro antioxidant activity which was further corroborated by in vivo antioxidant assessment through evaluation of SOD in excised paw tissue.

Effects of ciprofloxacin or co-amoxicillin with and without antidepressants on behavioral deficit in rats induced with chronic suppurative otitis media.

Chronic suppurative otitis media (CSOM) is chronic infection of middle ear which is usually managed with antibiotic therapy. This infection may cause the depression and cognitive changes in patients. The aim of present study was to evaluate the effect of antibiotic (ciprofloxacin and co-amoxicillin) with antidepressant or without antidepressants (bromazepam and imipramine) at low doses on rats with induced with CSOM. Pseudomonas aeruginosa was used to induce CSOM by in rat ear (tympanic bulla). The rats were divided into eight groups having six animals in each group. Neuropharmacological activities and gross behavior were observed in open field activity, force swimming cage, maze test, light and dark activity box and traction test. Observations were noted weekly after the administration of ciprofloxacin (15.3mg/kg), co-amoxicillin (15.3mg/kg), imipramine (1.15mg/kg) and bromazepam (0.09mg/kg) intraperitoneally. The altered behavior and depression was observed in control positive but reverted back in groups maintained on antidepressants with antibiotics with significant improved locomotor activity, memory in memory cage, muscular co-ordination and body balance and decreased anxiety. On the other hand, groups treated with only antibiotics showed significant improvement only in force swimming and traction test at day 14. Therefore, the antidepressant effects of the drugs can be employed to attenuate stress and depression in patients with CSOM.

Diclofenac sodium enhances the antiepileptic effect of levetiracetam in pilocarpine induced epileptic mice model.

Epilepsy, a neuronal disorder has affected 1% of the world's population. Almost 35-40% of these patients get resistant to available anti-epileptic drugs (AEDs). Recent studies have shown the role of inflammation in the pathophysiology of epilepsy and a combination of anti-inflammatory and antiepileptic drugs could prove beneficial against epileptic seizures. Therefore, we aimed to examine the effect of levetiracetam (LEV) and diclofenac sodium (DFS) combination on pilocarpine (PLC) induced epileptic seizures in mice. Mice were divided into control and treatment groups. LEV alone and in combination with DFS was given for 3 days. On 3rd day after administering the required drugs, pilocarpine challenge was given intraperitoneally. Then, behavioral changes were observed for 90 minutes, including latency to first seizure, continuous seizures, duration of continuous seizures, and survival rate. Results showed significant improvement in the latencies to first (P<0.001) and continuous seizures (P<0.05), duration of the continuous seizure (p=0.001), and survival rate (P<0.01) in the combination treatment group as compared to the control or individual drug treatment groups. DFS enhances the efficacy of LEV, however, further mechanistic studies will be required to conclude if DFS can be given in combination with LEV for epilepsy treatment.

Spectroscopic interactions of non-insulin-dependent diabetes mellitus with levocetirizine.

Non insulin dependent diabetes mellitus (NIDDM) drugs such as glibenclamide and metformin is employed to heterogeneous disorder characterized by alteration in production of glucose due to impairment of both insulin secretion and insulin action. These patients might suffer with allergic rhinitis and in this case, there is a possibility to maintain patient on levocetirizine, an anti-allergic drug commonly used in rhinitis. The object of the present study is to detect possible interaction between glibenclamide or metformin with levocetirizine Current study was performed using UV spectroscopic technique sing simultaneous equation in pH simulated to gastric juice (pH 1), pH 4, pH 7.4 and in pH 9. All drugs followed Beer Lambert's Law. Results showed that glibenclamide and metformin can increase or decrease availability of levocetirizine and in the same way levocetirizine can alter availabilities of glibenclamide and metformin in different pH. Hence, drug interaction between glibenclamide or metformin with levocetirizne occurred. This may be due to his may be due to the charge transfer or binding capabilities of these drugs which resulted in significantly changed availability of NIDDIM as well as levocetirizine. Therefore, co-administration of these drugs should be avoided and furtherinvestigations at clinical and pre-clinical levels should be done.

Hepatotoxicity induced by chronic suppurative otitis media in rats and effects of ceftazidime and amikacin on it.

Chronic suppurative otitis media (CSOM) is the chronic inflammation with perforation of middle ear. If CSOM is not treated, it may cause secondary inflammation of liver with elevated liver enzymes and histological changes. Present study is aimed to observe the hepatotoxic effects due chronic suppurative otitis media (CSOM) in CSOM induced rats and alsoto observe the effects of ceftazidime and amikacin to attenuate hepatotoxicity due to CSOM. Liver enzyme tests and histological examinations were performed on rats divided into different groups as G1 (negative control), G2 (positive control), G3 ceftizidime (15mg/kgintraperitonelly) and G4 amikacin (15mg/kg). One-way ANOVA showed that liver enzymes were significantly increased (p=0.000 and F value 6.899) except gamma glutamic transferase in G2 (rats with CSOM without treatment) from G1 (negative control without CSOM) with histological damage of liver. These hepatotoxic effects were attenuated or recover with proper treatment with potent antibiotics (ceftazidime and amikacin). Therefore, study showed that chronic suppurative otitis media can induce hepatic toxicity including elevated liver enzymes level and inflammation, aggregation or infiltration in liver cells in rat model with reversible hepatic damage. If CSOM is treated with adult dose of ceftazidime or amikacin, it may attenuate the damage and prevent risk of liver damage.

Spectroscopic interaction studies of H2 receptor antagonists with levocetirizine.

Patients with allergic rhinitis may also suffer abdominal pain, gastritis or peptic ulcer. In this condition patient may use levocetirizine with famotidine or ranitidine. These drugs have potential to interact with another drug and form complex. The aim of the present study is to evaluate the possible drug drug interaction with each other which may cause increase or decrease of therapeutic effects. For this purpose, validity of Beer Lambert law was checked, lone availability of famotidine (20gm), ranitidine (150gm) and levocetirizine (5mg) were studied in pH simulated to gastric juice (pH 1), pH 4, pH 7.4 and in pH 9 and finally percent availabilities of these drugs were calculated with the help of simultaneous equation. Results showed high percentage of levocetirizine in all pH as 300.32%, 514.41%, 173.38% and 220.68% in presence of famotidine but very low availability of famotidine as 5.36%, 35.38%, 51.87% and 10.89% in presence of levocetirizine. In the case of levocetirizine and ranitidine interaction, zero percent levocetirizine was available at pH 1and 9, 56.28% in pH 4 and 191.1% in pH 7.4. On the other hand, ranitidine was available as 95.36%, 127.93%, 41.47% and 144.3%. These results showed that percentage of all drugs were altered in presence of each other due to drug-drug interaction. This may be due to the charge transfer binding capabilities of the drugs which resulted in significantly changed availability of famotidine, ranitidine as well as levocetirizine.

Antibacterial, antifungal and enzymatic activities of azithromycin-heavy metal complexes: Newly synthesized and characterized.

As part of our continuous research to understand the interaction mechanism of drug and metallo-elements, heavy metal complexes of azithromycin (AZI) were synthesized with arsenic oxide, lead carbonate and silver chloride salts in molar ratio of 2: 1 (L: M). Synthesized heavy metal complexes have shown good percent yield and characterized through spectroscopic parameters including UV-Visible, TLC, FT-IR, NMR and elemental analysis (CHN). Spectroscopic characterization reveals the binding of ligand AZI with heavy metals in bi-dentate manner involving the hydroxide and 9a-NCH3 group of the aglycone ring of AZI. These newly synthesized heavy metal complexes were evaluated for their antimicrobial response against selected gram positive and gram negative organisms and antifungal species. It was noted that all newly synthesized complexes exhibits increased activity against B.subtilus whereas, AZI itself didn't show any activity, while synthesized complexes have low to moderate response against all the studied organisms. Complex A-M12 possess greater enzymatic response against both urease and alpha chymotrypsin among all the studied complexes. Results obtained were then statistically analyzed through one way ANOVA and Dunnett's test by using SPSS version 20.0 suggesting the significant response of complexes against selected organisms.

Anti-inflammatory and histopathological studies of leaves extracts of Croton bonplandianus in Albino rats.

Non-steroidal anti-inflammatory drugs (NSAIDs) are frequently used for the treatment and prevention of inflammation with the increase in number of side effects. Traditional plants have been used to treat inflammation owing to lesser adverse responses. Croton bonplandianus being an anti-inflammatory plant is extensively utilized all over the world. The methanolic and aqueous leaves extracts of Croton bonplandianus were exposed to anti-inflammatory activity in the carrageenan induced paw edema against standard diclofenac sodium, followed by the histopathlogical examination. The highest dose of methanolic extract were shown significant anti-inflammatory action having a significant P-value (P<0.05-0.001) compared with the diclofenac sodium (P<0.01-0.001) and aqueous extracts (P<0.5-0.01). The histopathological examination illustrated the vasodialation with reduction in the intensity of edema, neutrophils infiltration and other inflammatory cells. C. bonplandianus being a reactive oxygen species scavenger, responsible to exert an excellent anti-inflammatory activity. The present study confirmed the anti-inflammatory potential of drug extracts and authors recommended its utilization in the treatment of pain, inflammation and relevant diseases in future. However, phytochemical screening is to be required for the complete evaluation of active chemical constituent (s).

Prevalence and clinical/molecular characteristics of PTEN mutations in Turkish children with autism spectrum disorders and macrocephaly.

BACKGROUND: Phosphatase and tensin homolog (PTEN) germline mutations are associated with cancer syndromes (PTEN hamartoma tumor syndrome; PHTS) and in pediatric patients with autism spectrum disorder (ASD) and macrocephaly. The exact prevalence of PTEN mutations in patients with ASD and macrocephaly is uncertain; with prevalence rates ranging from 1% to 17%. Most studies are retrospective and contain more adult than pediatric patients, there is a need for more prospective pediatric studies. METHODS: We recruited 131 patients (108 males, 23 females) with ASD and macrocephaly between the ages of 3 and 18 from five child and adolescent psychiatry clinics in Turkey from July 2018 to December 2019. We defined macrocephaly as occipito-frontal HC size at or greater than 2 standard deviations (SD) above the mean for age and sex on standard growth charts. PTEN gene sequence analysis was performed using a MiSeq next generation sequencing (NGS) platform, (Illumina). CONCLUSION: PTEN gene sequence analyses identified three pathogenic/likely pathogenic mutations [NM_000314.6; p.(Pro204Leu), (p.Arg233*) and novel (p.Tyr176Cys*8)] and two variants of uncertain significance (VUS) [NM_000314.6; p.(Ala79Thr) and c.*10del]. We also report that patient with (p.Tyr176Cys*8) mutation has Grade 1 hepatosteatosis, a phenotype not previously described. This is the first PTEN prevalence study of patients with ASD and macrocephaly in Turkey and South Eastern Europe region with a largest homogenous cohort. The prevalence of PTEN mutations was found 3.8% (VUS included) or 2.29% (VUS omitted). We recommend testing for PTEN mutations in all patients with ASD and macrocephaly.

Horn on the Nail: Acquired Ungual Fibrokeratoma.

Acquired ungual fibrokeratomas are uncommon fibrous tissue tumors that are located in the ungual area. They usually presents as asymptomatic, solitary, smooth, dome-shaped, or fingerlike, flesh-colored papules accompanying nail deformities, including a longitudinal groove and trachyonychia. Acquired periungual fibrokeratoma is considered a topographical variant of acquired digital fibrokeratoma; it has a unique "garlic clove" shape. A traumatic origin has been suggested, as acquired ungual fibrokeratomas occur most frequently on the fingers and toes. Herein, we report a case of a 29-year-old man with growth over left little finger, who was treated with surgical excision of the tissue. Histopathological examination confirmed ungual fibrokeratoma. It is a rare variant of digital fibrokeratoma, and so far the first ungual fibrokeratoma to appear de novo on little finger to the best of our knowledge.

Incorporating a clinical oncology pharmacist into an ambulatory care pharmacy in pediatric hematology-oncology and transplant clinic: Assessment and significance.

BACKGROUND: Beta thalassemia patients, post-bone marrow transplant, and leukemia patients require long term therapy with an intense care follow-up especially for pediatric hematology-oncology origin. Emergence of side effects and noncompliance to therapy lead to reduced efficacy of medicines resulting in relapse of diseases. There is an increasing fact to support the incorporation of a pharmacist into clinical team due to their distinctive skills. Clinical oncology pharmacist with experience and specialized training in hematological cancers and bone marrow transplantation (BMT) patient care has in-depth knowledge and skills of chemotherapy regimens including drug information, monitoring parameters of cancer treatment, dose adjustment, drug-drug interactions, adverse effects, and patient counseling skills. AIM AND OBJECTIVES: The main objective of our study was to assess the significance of incorporation of clinical oncology pharmacist in ambulatory care in pediatric hematology-oncology and transplant clinic. MATERIAL AND METHOD: This study was conducted at National Institute of Blood Diseases and Bone Marrow Transplantation hospital with duration of five months from 17 March 2019 to 16 July 2019. In this study the clinical oncology pharmacist was made available at ambulatory clinic of hematology-oncology and transplantation. The activities performed by a clinical oncology pharmacist were observed by resident BMT clinical pharmacist during the visits of patients and their families in a clinic. The BMT pharmacist is a clinical oncology pharmacist with experience and specialized training in hematological cancers and BMT patient care. Only pediatrics patients with beta thalassemia major and those who were on chemotherapy treatment and post-transplant patient were included in this study. RESULTS: During the five months' tenure, there were 1820 pediatric patients' visits in total. The clinical oncology pharmacist performed 980 direct patient interviews and documented 1665 pharmacist interventions. The majority of the documented clinical oncology pharmacist interventions were review of medication histories (n: 404, 24%) and "deferiprone" dose adjustments (n:400, 24%). Genomic profiling interventions were also among the commonly reported activities by the clinical oncology pharmacist. For beta thalassemia patients undergoing hydroxyurea therapy, the genomic profiling was performed to assess whether the hydroxyurea treatment is clinically effective or not (n:396, 23%). CONCLUSION: The involvement of clinical oncology pharmacist into a specialized outpatient clinic of hematology-oncology and transplant clinic plays an integral role in minimizing the adverse effect and reduction in readmission into the hospital. This is new expansion of pharmacist's role especially in underdeveloped country, considering the relevant clinical participation of clinical oncology pharmacist into specialized clinic revealing through optimized therapy and future prospect of clinical oncology pharmacist in pediatric hematology.

GC/MS assisted phytochemical analysis of Ajuga parviflora leaves extract along with anti-hepatotoxic effect against anti-tubercular drug induced liver toxicity in rat.

Owing to its traditional applications, the current study focuses on Ajuga parviflora (A. parviflora) leaves extract for phytochemical and pharmacological analysis. The principle constituents were identified through gas chromatography (GC), and gas chromatography/mass spectroscopy (GC/MS), these includes phthalic acid, squalene, α-tocopherol, vitamin E, phytol, 2-methylenecholestan-3-ol, stigmasterol, cholest-22-ene-21-ol and 3,5-dehydro-6-methoxy. Hepatoprotective effect of A. parviflora was evaluated through isoniazid and rifampicin (INH and RFP) induced hepatotoxicity in rat. Animals in group A were treated with INH and RFP 50 mg/kg. Animals in group B, C, and D were pre-treated with A. parviflora extract at 100, 200 and 300 mg/kg dose prior drug administration. A. parviflora extract at 200 and 300 mg/kg in group C and D significantly reduced aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and bilirubin (p<0.001) as compare to group B (100mg/kg). Total protein (TP) was also significantly (p<0.01) reduced in group C and D at dose of 200 and 300 mg/kg, respectively. The extract pre-treated animals with (A. parviflora, 200, and 300 mg/kg) showed that the epithelium of the central portal vein is intact with replete glucagon. The pre-treatment with A. parviflora protected the liver from INH and RFP induced hepatotoxicity. The results of pre-treated animals with A. parviflora 200, and 300 mg/kg dose prettily revert the severely disturb parameters like, cytolysis, lymphocytic infiltration, and lymphoid aggregate in portal vein and hydropic degeneration. The decrease peroxisome proliferator-receptor activator-δ (PPAR-δ) gene expression by INH, and RFP was significantly up regulated by A. parviflora extract in pre-treated animals at 200 and 300 mg/kg dose. These findings provide baseline pharmacological uses of A. parviflora in liver disorders. Further investigations are required for identification and isolation of biologically active components responsible for pharmacological activity.

Field evaluation of a locally produced rapid diagnostic test for early detection of cholera in Bangladesh.

BACKGROUND: Cholera remains a substantial health burden in Asia and Africa particularly in resource poor settings. The standard procedures to identify the etiological organism V. cholerae are isolation from microbiological culture from stool as well as Polymerase Chain Reaction (PCR). Both the processes are highly lab oriented, labor extensive, time consuming, and expensive. In an effort to control for outbreaks and epidemics; an effective, convenient, quick and relatively less expensive detection method is imperative, without compromising the sensitivity and specificity that exists at present. The objective of this component of the study was to evaluate the effectiveness of a locally produced rapid diagnostic test (RDT) for cholera diagnosis. METHODS: In Bangladesh, nationwide cholera surveillance is ongoing in 22 hospitals covering all 8 divisions of the country since June, 2016. In the surveillance, stool samples have been collected from patients presenting to hospitals with acute watery diarrhea. Crystal VCTM (Span diagnostics, India) and Cholkit (locally produced RDT) have been used to detect V. cholerae from stool samples. Samples have also been sent to the main laboratory at icddr,b where the culture based isolation is routinely performed. All the tests were carried out for both direct and enriched stool samples. RDT sensitivity and specificity were calculated using stool culture as the gold standard. RESULTS: A total of 7720 samples were tested. Among these, 5865 samples were solely tested with Crystal VC and 1355 samples with Cholkit whereas 381 samples were tested with both the RDTs. In comparison with culture, direct testing with Crystal VC showed a sensitivity of 72% (95% CI: 50.6% to 87.9%) and specificity of 86.8% (95% CI: 82.8% to 90.1%). After enrichment the sensitivity and specificity was 68% (95% CI: 46.5% to 85.1%) and 97.5% (95% CI: 95.3% to 98.8%) respectively. The direct Cholkit test showed sensitivity of 76% (95% CI: 54.9% to 90.6%) and specificity of 90.2% (95% CI: 86.6% to 93.1%). CONCLUSION: This evaluation has demonstrated that the sensitivity and specificity of Cholkit is similar to the commercially available test, Crystal VC when used in field settings for detecting V. cholerae from stool specimens. The findings from this study suggest that the Cholkit could be a possible alternative for cholera endemic regions where V. cholerae O1 is the major causative organism causing cholera.

GC-MS profiling, FTIR, metal analysis, antibacterial and anticancer potential of Monotheca buxifolia (Falc.) leaves.

Monotheca buxifolia has traditionally been employed in folk medicines to cure of infectious diseases. Current study was aimed to standardize the M. buxifolia leaves extract and evaluate its antibacterial and anticancer activity. Phytochemical analysis was carried through GC, GC/MS, FTIR, and ICP-OES analytical techniques. Antibacterial assay of the crude extract was performed by using tetrazolium micro plates. The extract treated bacteria were observed under (AFM) atomic force microscope and PCR was used for DNA amplification. The anti-proliferative activity of M. buxifolia leaves extract was examined through MTT cytotoxicity assay. The bacterial strains employed in this study were S. epidermidis ATCC (13518), S. aureus ATCC (25923), P. aeruginosa ATCC (10145), and E. coli ATCC (10536). Minimum inhibitory concentration (MIC50) against gram positive bacteria was significantly (p<0.01) achieved at 50 and 75µg/mL. MIC50 against E. coli and P. aeruginosa was also significant at 100µg/mL (p<0.01). M. buxifolia leaves extract damaged the cell walls gram-positive and gram-negative bacteria, while biofilm around gram positive bacteria was significantly damaged. The DNA decantation was also inhibited of S. aureus and S. epidermidis, however, no any impact was observed on E. coli and P. aeruginosa DNA decantation. The cytotoxicity findings suggested that the crude extract of M. buxifolia leaves at 1000µg/mL gives significant inhibition 73.96±2.0%, 83.76±1.2%, 77.66±1.2% and 72.67±1.6% against MDA-MB-231, MCF-7, HeLa and H460 cell lines respectively at (p<0.001). It may be concluded that M. buxifolia leaves extract have significant and promising antibacterial and anti-cancer activities which could be helpful to establish new antimicrobial and anticancer agents.

Phytochemical screening and assessment of analgesic, Anti-inflammatory and hematological properties of the fruit of Berberis baluchistanica.

Traditionally Berberis species have been used as anti-inflammatory, anti-rheumatic, analgesic and anti-anemic drugs. This study was aimed to determine chemical constituents and to assess analgesic, anti-inflammatory and hematological effects of the crude extract of the berries of Berberis baluchistanica to verify these folkloric claims. Phytochemical screening, carried out by using different chemical reagents and techniques like Thin Layer Chromatography (TLC) and Fourier Transform infra-Red (FTIR) indicated presence of flavonoids, saponins, phytosterols and carbohydrates including reducing sugars. Analgesic and anti-inflammatory activities were assessed on mice by using acetic acid induced writhing method and formalin method. Potent anti-inflammatory and analgesic effects were observed during these experiments. The extract also showed anti anemic effect as it increased the levels of hemoglobin and red blood cells significantly. Increase in the platelet count was also noted. The extract of the berries was used at oral doses of 300 and 500 mg/kg during experiments. Anti-inflammatory and analgesic activities were determined by comparing with the standard i.e. aspirin 300 mg/kg. Both doses produced significant anti-inflammatory and analgesic activities at P<0.05. These activities were seemingly attributable to flavonoid and saponin contents of the drug. These results justify the folkloric claims that the drug could be used as good anti-inflammatory, antirehumatic, analgesic and anti-anemic drug. However, further chemical investigations on the drug are suggested for isolation and identification of compounds that could be safer and more effective than the currently available medicines in treating these disorders.

Evaluation of seroprevalence of Hepatitis B virus infection among patients attending a hospital of semi-urban North India using rapid immunoassay test.

BACKGROUND: Viral hepatitis is a serious public health problem with hepatitis B virus (HBV) being one of its principle causes affecting billions of people globally. The laboratory diagnosis of HBV infection is made by detection of hepatitis B surface antigen (HBsAg) in serum. OBJECTIVE: The present study was done to evaluate the seroprevalence of hepatitis B infection among patients attending a hospital at a semi-urban North India using rapid immunoassay test kit. MATERIALS AND METHODS: A total of 1537 patients were included in the study whose venous blood samples were collected, and serum was tested for the presence of HBsAg using a rapid one-step immunoassay test kit. RESULTS: Out of 1537 patients whose blood samples were tested, 61 were found to be reactive to HBsAg giving the prevalence to be 3.9%, with 49 males and 12 females. Out of 61 reactive patient's majority belonged to inpatient (82.0%) as compared to outpatient department (18.0%). The majority of the reactive patients belonged to age group 28-37 years (37.7%), belonged to rural areas (86.9%), were illiterate (67.2%), were skilled workers (63.9%) and belonged to socioeconomic Class 4 (50.8%). Among the reactive patients, the most frequent suspected risk factor for hepatitis B infection was found to be visiting a community barber (19.7%). CONCLUSION: HBV infection is a dreadful disease, and its accurate and timely diagnosis using rapid immunoassay test kit is useful as it gives an indication about its seroprevalence in a given geographical area even with limited resources.

Comparison of four diagnostic techniques for detection of Trichomonas vaginalis infection in females attending tertiary care hospital of North India.

BACKGROUND: Trichomonas vaginalis causes a common sexually transmitted disease trichomoniasis, which may lead to increased risk of transmission of human immunodeficiency virus infection and other pelvic inflammatory diseases. Wet mount examination is the most common test for diagnosis, but it has low sensitivity. Acridine orange staining can be used for diagnosis, but it requires special microscopic facility. Culture is considered as the gold standard, but it takes a long time for diagnosis. OSOM Trichomonas Rapid Test is a recently introduced rapid method based on immunochromatographic assay of trichomonal protein antigens. Hence, the present study was done to compare these four diagnostic techniques for detection of trichomoniasis in females with vaginal discharge. MATERIALS AND METHODS: Vaginal swabs were taken from 835 female patients and wet mount examination, acridine orange staining, culture in Kupferberg medium, and OSOM Trichomonas Rapid Test, were performed. RESULTS: Out of 835 patients included in our study, 68 (8.1%) positive cases of trichomoniasis were detected by culture. OSOM Trichomonas Rapid Test detected 63 (7.5%) cases, acridine orange staining detected 53 (6.3%) cases, whereas, wet mount examination detected only 45 (5.4%) positive cases. OSOM Trichomonas Rapid Test performed well and showed high sensitivity and specificity of 88.2% and 99.6%, respectively. CONCLUSION: As OSOM Trichomonas Rapid Test is a point of care test and gave better results than both wet mount examination and acridine orange staining; it can be used as a routine test in peripheral areas lacking laboratory facilities.

Phytochemical screening and anti-oxidant activity of the two plants Ziziphus oxyphylla Edgew and Cedrela serrata Royle.

Phytochemical studies of medicinal plants are a basic and helping tool for the isolation of active secondary metabolites. The isolation of active compounds is made easy by the help of preliminary phytochemical studies, which shows the presence of a specific class or group of compounds present in these medicinal plants.
