ABSTRACT
Mites act as the vectors of zoonotic vector-borne disease scrub typhus caused by the rickettsial pathogen Orientia tsutsugamushi. In India, scrub typhus is transmitted by the mite Leptotrombidium deliense. Rodents are the reservoirs and support the spread of this disease. Sarcoptes scabiei or the itch mite is causing scabies which is a common skin infection in India. Dermatitis, trombiculosis, and mite dust allergy are common mite-borne diseases transmitted by Pyemotidae family. D. brevis folliculorum and Demodex brevis are two major mite species found on humans also causing a disease; “Demodicosis”, common in India. Dermanyssus gallinae, fowl mite causes pruritis in poultry birds, transmits infections to poultry workers when they come into contact with birds. There is a re-emergence of mite-borne diseases, especially scrub typhus, in many parts of India requiring urgent attention for its control. This review is aimed to update the available information on mites and mite transmitted diseases prevalent in India to highlight the importance of rodent and chigger mite vector control to prevent forthcoming mite-borne diseases in India.
ABSTRACT
ABSTRACT Alcoholic foamy degeneration (AFD) is an uncommon presentation of alcoholic liver disease (ALD) with characteristic histologic findings of foamy-looking hepatocytes due to the presence of abundant microvesicles of fat within the cytoplasm predominantly in perivenular and midzonal regions without inflammation and fibrosis. It is underdiagnosed as the patients quickly recover after alcoholic abstinence and are rarely caught on biopsies. AFD has better prognosis than alcoholic hepatitis, and the injury mechanism is different, warranting a different diagnosis. We present an uncommon case of AFD incidentally diagnosed during autopsy in a chronic alcoholic and diabetic man.
ABSTRACT
Japanese encephalitis (JE) is a leading cause of viral encephalitis in Southeast Asia. It is a serious public health issue in India, and cases have been emerging in newer areas of the country. Although vaccination efforts have already been initiated in the country since 2006 and later through the Universal Immunization Programme in 2011, still a significant reduction in the number of cases has to be achieved since an escalating trend of JE incidence has been reported in certain States such as Assam, Uttar Pradesh and West Bengal. Moreover, fresh cases of JE have been reported from certain pockets in Odisha as well. Despite the mass JE vaccination programme implemented in prioritized endemic zones in the country in 2011, a shift in the age group of JE virus (JEV) infection was noticed affecting the adult population in West Bengal. The recent detection of the circulation of genotype I (GI) in Gorakhpur, Uttar Pradesh and the co-circulation of GI and genotype III (GIII) in West Bengal are probably a warning signal for the public health personnel to strengthen the surveillance system in all endemic hotspots in the country. The abrupt emergence of JEV genotype V (GV) in China and Korea in 2009, after its first detection in Malaya in 1952, endemic countries have been cautioned to strengthen their surveillance, because GV has been suspected of getting dispersed efficiently in other parts of Asia. Moreover, the reduced protection efficiency of the JEV GIII-based vaccine against the JEV genotype V further warrants careful evaluation of the ongoing vaccination strategies in the endemic countries, anticipating the possible incursion of GV and its impact on future control strategies. In view of the above facts, the present communication reviews the current knowledge on the molecular epidemiology of JEV in India vis-a-vis the global scenario and discusses the future priorities in JEV research in India for effectively designing control strategies.
ABSTRACT
Japanese encephalitis (JE) is a very serious public health problem in India and the conducive environment permit its emergence in non-endemic areas in the country. There are constant changes taking place in the pattern of current agricultural practices and vector breeding habitats which had far-reaching consequences on the epidemiology of JE and the severity of epidemic outbreaks today. Due to the continuous ecological changes taking place, vectors changed in their breeding dynamics, feeding, and resting behavior and started invading previously non-endemic areas. JE has recently spread to new territories due to land-use changes, including forest fragmentation and concentrated livestock production. Changes in the livestock population decreased the cattle pig ratio which enhanced the Japanese encephalitis virus (JEV) infection. This review brings forth the present widespread changes encountered that grossly impact the risk of infection in many places for the emergence of Japanese encephalitis and to address the implications for its control.
ABSTRACT
Background & objectives: Bacillus subtilis subsp. subtilis (VCRC B471) and Pseudomonas fluorescens (B426) produce mosquitocidal biosurfactant, surfactin and di-rhamnolipid. The objective of the study was to carry out a small-scale field evaluation of the two biosurfactants to determine the efficacy, application dosage, residual activity and frequency of application against Anopheles stephensi immatures in selected sites in Goa, India. Methods: Surfactin (VCRC B471) and di-rhamnolipid (VCRC B426) were formulated as aqueous suspensions (5% AS), and were applied at the dosages of 34, 51 and 68 mL/m2 and 27, 41 and 54 mL/m2 respectively. Two experiments were carried out with the two formulations. Results: Surfactin (VCRC B471) formulation was effective at all the dosages and there was sustained reduction (>80%) in immature density in the treated sites up to 18 days in experiment 1 and up to 15 days in experiment 2. No pupae were found in the treated sites throughout the study. Di-rhamnolipid (VCRC B426) formulation was also found to reduce the immature density in the treated sites up to 14 days in experiment 1 and up to 15 days in experiment 2. Interpretation & conclusion: For VCRC B471, the optimum application dosage determined was 51 mL/m2 and for VCRC B426, 27mL/m2 . The formulations are to be applied fortnightly for effective control of Anopheles. The application dosage determined in the present study can be used for large scale field evaluation to assess their suitability for use in public health programmes for the control of Anopheles mosquitoes vectoring malaria
ABSTRACT
Lymphatic filariasis (LF) is a vector-borne neglected tropical disease, causing permanent disability. The disease is debilitating and widespread, leading to tremendous productivity and economic loss. The Government of India (GOI) prioritized the elimination of LF through the annual mass drug administration (MDA) programme in 2004 and continued with a single dose of diethylcarbamazine citrate (DEC), 6 mg/kg of body weight, plus albendazole annually over a period of 5-6 years. The GOI had set the target to achieve LF elimination by 2015 and now by 2030. The progress so far has been suboptimal. Much remains to be done as about 84 per cent of the total 328 endemic districts are still under MDA. The major challenge in implementing MDA is poor compliance. It is necessary to have a feasible alternative strategy addressing the above challenge to achieve the desired goal of LF elimination. At this juncture, a well-researched approach, i.e. the use of DEC-fortified salt, also advocated by the World Health Organization, as a unique form of MDA, is proposed. As per this strategy, a low dose of DEC (0.2% w/w) is added to the cooking salt at the manufacturing facility of iodized salt and consumed by the LF-endemic communities for about two years. Many examples of successful use of this strategy for LF elimination in small- and large-scale trials have been documented in India and several other endemic countries in the world. Implementing DEC–iodine-fortified salt is a safe, less expensive, more efficient and prompt approach for achieving the elimination of LF in India. Adverse effects are none or minor and self-limiting. The DEC-fortified salt strategy can easily piggyback on the existing countrywide deployment of iodized salt under the National Iodine Deficiency Disorders Control Programme (NIDDCP), which has achieved a great success in reducing iodine-deficiency disorders such as hypothyroidism. This existing robust programme can be leveraged to launch DEC-fortified salt for the community. If implemented appropriately, this strategy will ensure the complete cessation of LF transmission within two years from its introduction. If the said strategy is implemented in 2022, it is expected that India will be able to achieve the LF elimination by 2024, much before the global target of 2030.
ABSTRACT
Ascertaining the genetic variability and its relationships among valuable genetic resources is important for crop improvement programme. Here, we assessed the response of eleven wheat (Triticum aestivum L.) genotypes using cluster and principal component analysis (PCA) based on morphophysiological data and yield under nine different environments. Wheat genotype WH 1080 maintained higher photosynthetic efficiency under individual stress of 50% water deficit (drought) and 100 mM NaCl (salt), whereas under interactive stresses KRL 370 and KRL 283 were found to be the best genotypes. The highest value of Na+/K+ ratio in shoots was recorded for WH 1080 (1.167) and lowest in KRL 283 (0.612) under combined stresses. Proline accumulation was maximum in KRL 330 (3.17 mg g-1 FW) and minimum in KRL 283 (2.8 mg g-1 FW). Significantly higher reduction (73.4%) was observed in HD 2009 for grain weight/plant at 100 mM NaCl + 50% WD stress treatment whereas minimum reduction of 39.18% was recorded in KRL 370 in comparison to the control treatment. The PCA showed that the first three components comprising about 91% of the total variation for which the variables were analyzed. AMMI model revealed KRL 210 to be stable genotype as being close to center on biplot. E5 environment (100 mM NaCl) was most stable followed by E9 (50% WD + 100 mM NaCl). HD 2888, C-306, HD 2851 and HD 2009 were having positive interaction with E1 (Control) whereas WH 1080 had positive interaction with water deficit environments i.e. E2 and E3 (25 and 50% WD) while KRL 433 had highest positive interaction with combined water deficit and salt stress environments E6, E7, E8 and E9, followed by KRL 370. Similarly, KRL 283, KRL 330, KRL 210 and Kharchia 65 had high positive interaction with saline environments E4 and E5. Findings of the experiment would be beneficial to wheat breeders, specifically the location-specific promising genotypes could possibly be used to develop/breed MAGIC populations to tag genes/alleles conferring drought and salinity tolerance.
ABSTRACT
Background & objectives: Accurate mosquito species identification is the basis of entomological surveys and effective vector control. Mosquito identification is either done morphologically using diagnostic features mentioned in taxonomic keys or by molecular methods using cytochrome oxidase subunit 1 (coxI) and Internal transcribed spacer 2 (ITS2). Methods: We performed a larval survey for Aedes mosquitoes from eight different geographical regions in Tamil Nadu, India. The mosquitoes collected during the survey were characterized using both morphological and molecular markers. Results: During an entomological survey from eight different geographical regions in Southern India, a morphological variety named Aedes aegypti var. luciensis was observed. The variant mosquitoes were characterized using both morphological and molecular markers. The variant mosquitoes differed only in the dark scaling of 5th segment of hind-tarsi. Around one third to two third of the 5th segment in variant mosquitoes was dark which has been described as white in identification keys. No other significant difference was observed in adults or immature stages. The variation was heritable and coexisting in the field with the type form mosquitoes. Comparison of the genetic profile of coxI and ITS2 were similar in variant and the type form indicating both of them to be conspecific. Interpretation & conclusion: The morphological variant mosquitoes were found genetically similar to the Ae. aegypti type form. However, considering its high prevalence and coexistence with Ae. aegypti type form in different geographical regions, detailed studies on bionomics, ecology, genetics, behavior as well as its plausible role in disease transmission are warranted.
ABSTRACT
eas (Insecta, Siphonaptera) are important vectors of plague and murine typhus in many parts of the world. Currently, about 2700 flea species were described in the world. The most common vector flea Xenopsylla cheopis is found throughout India, but X. astia, and X. brasiliensis are found less and limited in distribution associated with the domestic rats such as Rattus rattus, R. norvegicus, Mus musculus, and Bandicota bengalensis. Bubonic plague is a major flea-borne disease caused by the bacterial pathogen Yersinia pestis, transmitted from rats to humans via the rodent flea, X. cheopis. A major outbreak of plague and high mortality occurred in India. After 1966 with the 3 decadal intervals, plague cases occurred only during the year 1994 reported in 5 different states (Gujarat, Maharashtra, Karnataka, Uttar Pradesh, Madhya Pradesh and New Delhi and subsequently plague cases occurred during 2002 and 2004 after the one-decade interval in Himachal Pradesh (2002). Another outbreak of bubonic plague was reported in Dangud village, Barkhot tehsil, Uttarkashi district, Uttarakhand during October 2004. Ctenocephalides fleas are common in cats and dogs, which are the main vectors of bacteria rickettsiae, such as Rickettsia typhi, R. felis, R. conorii, and Bartonella henselae. Molecular and serological evidence also confirms the presence of R. typhi, R. conorii R. felis and B. henselae pathogens in cats and other fleas in India. Flea bites and flea-borne dermatitis are common in men and pet animals. Because of the re-emergence of the plague, updated information on fleas and flea-borne diseases are essential to control the flea vectors and flea-borne diseases in India. Hence, this comprehensive review updates the available information on fleas and fleas transmitted diseases in India.
ABSTRACT
Dengue, a vector-borne disease remains as one of the most serious public health problems globally. Incidence of this disease is on an increasing trend and currently over a billion people in tropical and subtropical regions are at risk. In the absence of an operational vaccine, prevention of dengue virus (DENV) is primarily focused upon controlling mosquito vectors. Mosquito vector surveillance programmes require simple and rapid tools to detect mosquitoes infected with DENV. Here, we tested the commercially available DENV Detect™ NS1 ELISA kit (InBios International, Inc.) for detection of recombinant DENV-NS1 protein in Aedes mosquito samples. The kit was evaluated to find out the minimum detection limit of recombinant DENV-2 NS1 protein following the manufacturer’s instructions. Initially, the NS1 protein detection threshold of the kit was determined and later the assay was standardized for detection of NS1 protein in Aedes aegypti mosquito pools containing 5, 10 and 25 mosquitoes. The ELISA kit displayed high sensitivity towards detection of recombinant dengue virus-2 NS1 protein in mosquito pools (up to 25 mosquitoes per pool) at 25 pico gram concentration. Since the commercial NS1 ELISA is highly sensitive and follows a very simple procedure, it could be employed for DENV surveillance in Aedes aegypti mosquitoes, after carrying out laboratory and field bioassays with DENV infected specimens.
ABSTRACT
Central Venous Catheters (CVCs) are indispensable in current intensive care treatment; also pose a greater riskof device related infections in comparison to any other type of medical device and are major cause of morbidity,mortality and increased expense. A cross sectional prospective study of one year duration was conducted inthe tertiary care University Hospital ICU located in the rural region of Haryana, India, to determine the incidenceof the central venous catheter related bloodstream infection (CRBSI), rate of catheter colonization and toidentify the associated risk factors and the microbial spectrum of CRBSI along with the antimicrobial sensitivitypattern of microbial isolates. Sixty patients with central venous catheter inserted and admitted under ICUhaving signs and symptoms of septicaemia post 48 hours of central venous catheter insertion were included.The rate of CRBSI was assessed by paired quantitative blood culture method in the CVC and peripheral vein.The CRBSI incidence was 16.67% and catheter colonization was found to be 53.3%. Methicillin-resistantstaphylococcus aureus and Acinetobacter baumanni were the predominant isolates. A statistically significantassociation of duration of catheterization with CRBSI was found. It is concluded that CRBSI incidence ishigh, with significant association of prolonged duration of catheterization with CRBSI. By knowing the changingtrends of microbial flora, empirical therapy can be formulated for early and effective management of CRBSI.
ABSTRACT
Soil salinization and alkalinization frequently co-occur in nature, but very few studies focus on the interactive effects of mixed salt and alkali stresses on plants. Sporobolus marginatus Hochst. ex A. Rich. (perennial halophytic grass) collected from extreme saline sodic Kachchh plains, Bhuj, Gujarat was analyzed to evaluate the stress specific responses in osmoprotectants, antioxidants, ionic relations and protein profiling under saline, sodic and mixed saline-sodic soils. Osmotic adjustments in terms of total soluble sugars (TSS), glycine betaine, proline content and protein concentration exhibited differential responses to variable stress conditions. Proline content increased 4.8 folds at pH2 10.0, 5.2 folds at ECe 35 dSm-1 and 5 folds at pH2 9.0 + ECe 20 dSm-1. The greater accumulation of proline in Sporobolus, may presumably be one of the factor for tolerance to higher salt. At the same time, superoxide dismutase (SOD) activity in leaves increased with increasing sodicity i.e. 30.73 and 33.55 units g-1 FW at pH 9.5 and pH 10.0, respectively. Gradual increase in peroxidase enzyme (POX) activity was observed under all the stresses. Under control condition, POX activity was 21.67 units g-1 FW in Sporobolus, which increased to 26.56 units g-1 FW at pH 10.0, 27.89 units g-1 FW at ECe 35 dSm-1 and 27.44 units g-1 FW at pH 9.0 + ECe 20 dSm-1. The basal activity of APX increased with increasing stress conditions and was maximum (43.91 units g-1 FW) at pH 10.0. On the other hand, 2 times higher glutathione reductase (GR) activity was obtained under sodic stress of pH 9.5 and pH 10.0. SDS-PAGE revealed that five new polypeptide bands of MW 58.5, 53.7, 39.7, 31.8 and 28.3 kDa were expressed at higher saline level while one polypeptide band of 39.7 kDa disappeared at higher salinity level of 35 dSm-1 which may be due to its degradation at higher salt concentration. Synthesis of common polypeptides of MW 98.1, 69.3, 35.45, 24.89 and 23.3 kDa under all the stress conditions need special mention. Furthermore, the enhanced expression of these proteins, which also existed in the control plants, were specifically increased under stress condition which revealed that these proteins were up-regulated in specific regions of Sporobolus adapted to salt stress. Therefore, further exploration is needed to test the contribution of salt stress related proteins/genes or regulatory factors from the salt tolerant grasses (STGs) for possible utilization in cereal crop improvement.
ABSTRACT
Background: Neonatal' sepsis' is' a' clinical syndrome' characterized by signs and symptoms' of' infection' with' or' without' accompanying' bacteremia' in' the' first' month' of' life. Neonatal' sepsis' may' be' classified' into' two' groups : early onset' sepsis and' late onset' sepsis . Early onset neonatal sepsis' is' generally' associated' with' the' acquisition' of' microorganisms' from' the' mother' and' usually' presents' with' respiratory' distress' and' pneumonia.Methods: The study included one hundred' term' neonates with early onset neonatal sepsis. A septic screen including total leukocyte count, absolute neutrophil count, blood smear evaluation, blood cultures and C-reactive protein (CRP) were performed in all neonates with suspected sepsis to corroborate early onset sepsis diagnosis. Epidemiological parameters including gender of the neonate, mode of delivery, rural/urban residence were recorded in addition to clinical profile.Results: Respiratory distress was the most common presentation in the form of tachypnea, seen in 63 (63.0%) neonates. In present study, Staphylococcus aureus was the most common organism isolated followed by Staphylococcus epidermidis, Staphylococcus hominis, Acinetobacter baumannii and Klebsiella pneumonae.Conclusions: Early onset neonatal sepsis' was seen more in males. Among the gram-positive Staphylococcus aureus and among gram negative Acinetobacter baumannii and Klebsiella pneumonae were most common organisms to be isolated.
ABSTRACT
Background: Routine childhood immunization is a proven tool for eradicating and controlling infectious diseases. Despite its key role in maintaining global public health, many individuals either refuse or delay immunization because of pain from the needle puncture. Several methods have been employed to reduce injection pain during immunization in children.Methods: Study comprised of 210 healthy infants coming for immunizations. They were divided into three groups A, B and C having equal number of infants. Group A was given oral sucrose solution, group B was given topical anaesthetic prior to immunization; whereas group C acted as controls. Response to pain was recorded among the three groups and findings were analyzed.Results: Infants enrolled in group A, i.e. those who were given 24% oral sucrose solution before immunization showed significant reduction in pain (measured by modified behaviour pain scale) as compared to control group at 15 seconds and 60 seconds of injection administration. Infants enrolled in group B, i.e. those who were sprayed topical local anaesthetics (10% lignocaine spray) before immunization showed significant reduction in pain as compared to control group at 15 seconds and 60 seconds of injection administration.Conclusions: Administration of oral sucrose solution and application of topical local anaesthetics are effective measures to reduce injection pain during immunization. Administration of oral sucrose solution before immunization showed greater reduction in pain as compared to application of topical local anaesthetics in present study.
ABSTRACT
Aim: 1) To study the outcome of hypoglycemia in neonates weighing >1500gram both symptomatic and asymptomatic having exclusively hypoglycemia with no any other medical condition known to cause brain damage , till 9 months of corrected gestational age(CGA).2) To study the clinical profile of hypoglycemia in neonates weighing >1500gram. Methods: 35 neonates weighing >1500gram with hypoglycemia (<40 mg/dl), both symptomatic and asymptomatic without any other medical condition known to cause brain damage were enrolled in the study. Hypoglycemia was confirmed with venous sample laboratory value. Both neonatal and maternal history was taken in detail, clinical examination, anthropometry was done. Follow up was done at 3, 6, 9 months of CGA for assessing neurodevelopmental outcome (motor developmental quotient i.e. MoDQ and mental developmental quotient i.e. MeDQ using DASII6 i.e. development assessment scale for Indian infants) and we did anthropometry and clinical examination, ultrasonography at discharge, electroencephalogram (EEG) done in patients with seizure, Magnetic Resonance Imaging (MRI) at 3 months, Brainstem evoked response audiometry (BERA) at 6 months, vision assessment at 9 months of CGA. Appropriate statistical analysis was done to calculate results. Results: Out of 35 enrolled cases follow up was possible in 30 cases. In our study, the prevalence of abnormal neurodevelopmental outcome according to DASII6 was 53.33% (n=16) cases with abnormal MoDQ (<70%) and 56.66% (n=17) cases with abnormal MeDQ (<70%) at 3, 6, 9 months of CGA respectively. There was statistically significant difference in the mean values of MoDQ (p value 0.014, 0.011, 0.02) and mean MeDQ (p value 0.019, 0.008, 0.02) on follow up at 3, 6, 9 months of corrected gestational age respectively between symptomatic and asymptomatic hypoglycemic cases. 8 (57.14%) symptomatic cases and 6 (37.5%) asymptomatic cases had microcephaly on follow up and the difference was not statistically significant. MRI was abnormal in 10 (71.4%) symptomatic cases and 6 (37.5%) asymptomatic cases and the difference was not statistically significant. Ultrasonography was done in all cases at discharge and it was found abnormal in 2(5.7%) cases. BERA, vision assessment and EEG was normal in all cases. Conclusion: Both symptomatic and asymptomatic hypoglycemia leads to abnormal neurodevelopmental outcome but it is more poor in symptomatic neonates as compared to asymptomatic hypoglycemia.
ABSTRACT
Background: Vitamin D is a fat-soluble steroid hormone. Vitamin D also has immunomodulatory effects on immune function. Early onset sepsis (EOS) is characterized by signs and symptoms of infection with or without accompanying bacteremia in the first three days of life. The objective of the study was to determine the possible association between neonatal vitamin D levels and EOS in term neonates.Methods: 100 term neonates with clinical and laboratory findings of EOS (study group) and 100 healthy infants with no signs of clinical/laboratory infection (control group) were enrolled. Sera was drawn during first 3 postnatal days of life in both groups for measurement of 25-hydroxyvitamin D (25-OHD) levels.Results: Neonatal 25-OHD levels (17.4ng/dL) in the study group were significantly lower than those of the control group (26.8 ng/dL) (p=0.001). In present study negative correlation was found between vitamin D level and CRP.Conclusions: Lower neonatal 25-OHD levels are associated with EOS. Adequate vitamin D supplementation during pregnancy may be helpful to prevent EOS in term neonates.
ABSTRACT
Soil salinization and alkalinization frequently co-occur in nature. However, only few studies have focused on the interactive effects of mixed salt and alkali stresses on plants. To find supplementary feed source under arid and semiarid conditions, Dichanthium (Forsk.) Stapf. seeds and root cuttings were collected from extreme saline sodic Kachchh plains, Bhuj (Gujrat), and established at ICAR-Central Soil Salinity Research Institute, Karnal. The experiment was designed in RBD having nine different treatments i.e. control (pH2: 7.1; ECe: 0.43), alkaline (pH2: 9.5 and 10.0), saline (ECe: 15, 25 and 35 dS m-1) and saline-alkaline (pH2 9.0 with ECe: 10, 15 and 20 dS m-1). Under alkaline conditions, Dichanthium maintained their plant height but reduction was observed in chlorophyll concentration at both the stresses. Highest photosynthetic rate (Pn) was recorded in control treatment i.e. 36.05 μmol CO2 m-2 s-1 which was decreased with the intensified stress. Reductions were also noticed in the rates of stomatal conductance (gS) and transpiration rate (E) under different stress levels. Dichanthium restrict Na+ accumulation (mean Na+ 0.27%) in root zone whereas in shoots, mean Na+ was 4.58%. Dichanthium maintained or increased shoot K+ concentration under saline and mixed stress condition to mitigate the injurious effect of high Na+ concentration. Among fodder quality parameters, Dichanthium contained 5.15% mean crude protein (CP). Stress treatment caused 10-25% reduction in the CP content over all the stress treatments. Alkalinity, salinity and mixed saline sodic stress caused reduction in neutral detergent fiber (NDF) content but maximum reduction was observed under salinity stress condition. ADF (Acid detergent fiber) content was higher in control (47.44%) and decreased with increasing salt stress. ADL followed the same the trend as shown by ADF.
ABSTRACT
Background: A prospective study was conducted in the Department of Pathology, GMC Patiala for two years on 60 patients with swellings of jaw seeking consultation in Rajindra Hospital, Patiala. Methods: Fine Needle Aspiration Cytology (FNAC) was done on all these patients followed by microscopic examination of the prepared slides and relevant clinical information was collected. The data was compiled and analysed statistically. In lesions where surgery followed FNAC, the comparison was done with histopathology and statistical values were calculated. Results: The results of the study were: non-neoplastic cases were 51.7% and neoplastic cases were 48.3%. Maximum cases were of chronic sialadenitis (30%) followed by pleomorphic adenoma (23.3%). Parotid gland was involved in maximum cases (60%). Biopsies or specimens for histopathological examination were received for 30 cases; maximum cases of which were diagnosed as pleomorphic adenoma on histopathology. Among malignant tumors, mucoepidermoid carcinoma was the most common. Conclusion: On correlating the cytological and histopathological nature of salivary gland lesions, sensitivity of FNAC came out to be 75%, specificity 100% and accuracy was calculated as 93.3%.
ABSTRACT
ABSTRACTThe present investigation was aimed to detect the specific polypeptide(s) appeared during the sequential stages of differentiation. Among different explants, only nodal explants showed good results for callusing. Depending on the fresh and dry weight, best callus growth was observed on MS medium supplemented with NAA (2.5 mg/L) inDioscorea alata and 2, 4-D (2.0 mg/L) inD. deltoidea, respectively. This callus was used for the regeneration. Roots differentiation was observed on MS medium + NAA (2.0 mg/L) + IBA (0.5 mg/L) and shoots on MS medium + BAP (2.0 mg/L) + NAA (0.5 mg/L) in D. alata while in D. deltoidea, roots on RT medium + IAA (1.0 mg/L) and shoots on RT medium + BAP (1.0 mg/L) + NAA (0.5 mg/L). Continuous decrease was seen in the total soluble protein during the differentiation inD. alatawhereas inD. deltoidea, the protein content decreased upto initiation stage. Four root specific polypeptides (MW 25.56, 24.35, 19.13 and 18.2 kDa) and three shoot specific polypeptides (MW 53.7, 25.12 and 19.13 kDa) were synthesized during the differentiation inD. alata. Similarly, two root specific (MW 33.9 and 31.69 kDa) and one shoot specific (MW 16.98 kDa) polypeptide band were appeared during differentiation in D. deltoidea.
