ABSTRACT
SUMMARY: The aim of the present work was to study the closer effect of clomiphene citrate on the ultrastructure of the testis of adult albino rats to provide a basis for optimizing this drug in the treatment of male infertility. The testes were removed from both groups under anesthesia and then prepared for examination by light using hematoxylin and eosin stains and a transmission electron microscope. Semithin sections were cut into 1 µm thick sections, stained with toluidine blue, and examined by light microscopy for a survey. The desired areas were placed in the center, and other areas were trimmed. Primary spermatocytes showed marked nuclear changes (pyknosis), and their nuclear membranes were ill-defined and disrupted. The cytoplasm showed widespread degeneration of mitochondria and lysosomes and focal degeneration of the rough endoplasmic reticulum compared with the control group. The spermatids were pale, and the two phases of spermatogenesis were distinctly identifiable in the control group but were confused in the treated group. Some spermatids had interrupted nuclear membranes, also containing degenerated mitochondria, focal fragmentation of rough endoplasmic reticulum, and free ribosomes. Spermatozoa in the treated group appeared deformed compared to the control, where they had deformed head caps. Leydig cells of the treated group have an irregularly shaped nucleus, with focal chromatin aggregation and peripheral chromatin condensation on the inner surface of the nuclear membrane. The observations of the present work indicate a possible causal relationship between testicular affection and ingestion of clomiphene citrate, which can be avoided by close medical observations using ultrasonography, semen analysis, or testicular biopsy to detect early malignant changes. Furthermore, the drug should not be used for more than three to six cycles and should be stopped for at least three cycles before reuse. When clomiphene citrate is ineffective in the treatment of male infertility, human menopausal gonadotropin (hMG) administration is typically selected. However, high-dose hMG therapy is associated with a variety of adverse effects. In this work, we report the success of a modified clomiphene citrate regimen in increasing sperm count without any hazards to the testicular tissue.
El objetivo del trabajo fue estudiar el efecto del citrato de clomifeno sobre la estructura de los testículos de la rata albina adulta, con la finalidad de determinar la mejor manera de utilizar este fármaco en el tratamiento de la infertilidad masculina. Los testículos se extrajeron bajo anestesia y para su análisis a través de microscopio de luz se tiñeron con HE. Además, las muestras fueron preparadas para su examen con microscopía electrónica de transmisión. Por otra parte, se cortaron secciones semifinas de 1 µm de espesor, se tiñeron con azul de toluidina y se examinaron mediante microscopía óptica. Los espermatocitos primarios mostraron cambios nucleares marcados (picnosis) y sus membranas nucleares estaban mal definidas y alteradas. En el grupo experimental las células presentaban el citoplasma con degeneración generalizada de las mitocondrias y de los lisosomas y una degeneración focal del retículo endoplásmico rugoso en comparación con el grupo control. Las espermátidas estaban pálidas y las dos fases de la espermatogénesis eran claramente identificables en el grupo control, pero se confundían en el grupo tratado. Algunas espermátidas tenían membranas nucleares interrumpidas, y también contenían mitocondrias degeneradas, fragmentación focal del retículo endoplásmico rugoso y ribosomas libres. Los espermatozoides del grupo tratado se presentaban deformados en comparación con el control. Las células de Leydig del grupo tratado presentaban un núcleo de forma irregular, con agregación focal de cromatina y condensación de cromatina periférica en la superficie interna de la membrana nuclear. Las observaciones del presente trabajo indican una posible relación causal entre la afección testicular y la ingestión de citrato de clomifeno, que puede evitarse mediante observaciones médicas minuciosas a través de ecografía, análisis de semen o biopsia testicular para detectar cambios malignos tempranos. Además, el medicamento no debiera ser usado durante más de tres a seis ciclos y debe suspenderse durante al menos tres ciclos antes de volver a usarlo. Cuando el citrato de clomifeno es ineficaz en el tratamiento de la infertilidad masculina, normalmente se selecciona la administración de gonadotropina menopáusica humana (hMG). Sin embargo, la terapia con hMG en dosis altas se asocia con una variedad de efectos adversos. En este trabajo, informamos el éxito de un régimen modificado con citrato de clomifeno para aumentar el recuento de espermatozoides sin riesgo para el tejido testicular.

Effects of aqueous seed extracts of Sphenostylis stenocarpa on the reproductive indices of male rats were investigated. A total of 104 adult rats were used for the experiment, and were divided into 4 groups (group A – D) and replicated in triplicate. Group A served as the normal control, while groups B, C and D received three graded doses (800mg/kg, 1200mg/kg and 1600mg/kg) of the extracts, respectively, by oral intubation. The gonad characteristics, sperm parameters and hormonal analyses of the male rats were determined using standard procedures. These were ascertained prior to the commencement of treatment, and on weekly basis. Data were analyzed statistically using SPSS and R software at 95% confidence interval. An overall dose and time dependent showed significant differences in the mean weekly gonad characteristics of the male rats in the treatment groups when compared with the control. There was a significant reduction (p < 0.05) in the body weights of the male rats, but a significant increase (P < 0.05) in the testes weights, gonad somatic index, sperm count and sperm motility in the rats. The gonadal hormone testosterone, responded to the plant extracts, while follicle-stimulating and luteinizing hormones were largely undetected. There were significant increases in the testosterone levels of all the treated rats. Conclusively, aqueous seed extracts of Sphenostylis stenocarpa seems to possess ability to enhance reproductive health in male rats.
ABSTRACT
Paraquat is a highly toxic chemical used in weed control. Paraquat is known for its ability to generate reactive oxygen species that attack cells and membranes. Vitamin E is a group of vitamins which dissolves in fat and possess antioxidant properties which act as a defense to the cells against oxidative stress arising from reactive oxygen species, whereas Vitamin C is a water soluble vitamin and a very potent antioxidant which protects the cells of the body from free radicals. The study aim was to evaluate the ameliorative effects of a combination therapy of vitamin E and C on biochemical markers of paraquat induced male albino rats. 200 male albino rats with 0.2±0.02 kg mean weight were used. The 200 rats were divided into four main groups with 50 rats within a group. The groups were labeled A, B C and D. The “A” group was neutral; “B” group was induced with 0.02 g, “C” 0.06g, and “D” 0.06 g of paraquat per kg rat every two weeks for three months. The main groups further had subgroups. “A” group had “A0” and “AVEC” subgroups; “B” group had “B0” and “BVEC” subgroups; “C” group had “C0” and “CVEC” subgroups; “D” group had “D0” and “DVEC” subgroups. “A0”, “B0”, “C0” and “D0” subgroups were not administered with vitamin E + C therapy while “AVEC”, “BVEC”, “CVEC” and “DVEC” were treated orally with 500 mg of vitamin E weekly and 2000 mg/l of vit C medicated water for one month. After then, the rats were sacrificed, blood samples were collected and analyzed for the liver function; T. bilirubin, D. bilirubin, T. protein, albumin, and globulin. ANOVA intergroup comparison of A0, B0, C0 and D0 was statistically significant, p-value<0.05 except for globulin. Intergroup comparison of AVEC, BVEC, CVEC and DVEC was statistically significant, p-value<0.05 except for globulin. Intra-group comparison showed significant difference only in total bilirubin and conjugated bilirubin levels, p-value<0.05. This study therefore has shown that weekly treatment with Vit E + C in one month can treat liver toxicity in rats.
ABSTRACT
The purpose of this research was to find out the growth performance of albino rats orally administered with honey from Apis mellifera adansonii and refined granulated sugar at varying quantities. Twenty-five (25) healthy albino rats used in the study were grouped into five treatments based on the dose of natural honey and granulated sugar as follow: T1 (1.02g of honey kg BW), T2 (1.40g of honey kg BW), T3 (1.02g of granulated sugar kg BW), and T4 (1.40g of granulated sugar kg BW). However, rats in T5 were not administered honey and refined granulated sugar hence served as the control. The data on fructose and micronutrients concentrations of natural honey and refined sugar as well as data on the weight gain and feed intake of the albino rats were determined after 28 days. According to the findings of this study, the fructose concentration was higher in natural honey (195.78mg/ml) while refined sugar (30.225mg/ml) recorded the least value. Also, copper (0.15ppm) and manganese (0.05ppm) had the highest mean concentration in natural honey, while iron (0.04ppm) and zinc (0.07ppm) were higher in refined sugar. The study's findings revealed that the highest feed intake by albino rat was recorded in T1 (148.16g) while T5 (140.27g) had the least. There were no significant differences in albino rat feed intake among the five treatments (p>0.05). The highest weight gain was recorded by the albino rat in T1 (69.84g) while T5 (32.28g) had the least. There were no significant differences in the weight gain of the albino rats among the five treatments. This study's findings led to the conclusion that the doses of natural honey used did not significantly increase the weight gain of albino rats.
ABSTRACT
Objective: To determine the anti-hyperglycemic effects of interleukin-1 inhibitor (diacerein) in alloxan induced diabetic albino wistar rats. This experimental study was performed at the Department of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University, Tando Jam within 6 months from April 2016 to September 2016. Total of 160 adult Albino Wistar Rats having an average of 200 to 300 grams body weights were selected. Animals were categorized into 4 groups as; Group A (n=15): Control rats – receive 0.9% normal saline as placebo Experimental Groups Group B (n=15): Experimental Control (Diabetic rats) - Alloxan50 mg/kg body weight intraperitoneal. Group C (n=15): Diabetic rats + Diacerein (30 mg/kg/day) orally daily. Group D (n=15): Diabetic rats + Diacerein (50 mg/kg/day) orally daily. Animals were kept and treated as per the NIH Guideline for Use and Care of Laboratory Animals. Diabetes mellitus was induced via a single intraperitoneal injection of 50 milligram/kg alloxan monohydrated dissolved in aseptic 0.9% saline. After 72 hours, blood specimens were taken from the caudal vein of the rats and glucose level>200 mg/dL was taken as diabetes. Experimental rats were given diacerein approximately 30 and 50 mg orally for 6 weeks. At the completion of experiment the body weight was measured of each animal by electronic measuring balance and blood sample was taken from each animal of all groups to assess the blood glucose level and HbA1c level. Data were recorded via self-made proforma and analysis was done by using SPSS version 20. Results: Average body weight of Diabetic control (Group B) was 193.33±22.50 grams, which was lower in contrast to Diacerein treated group C 202.47±25.70 grams and significantly lower as compared to Diacerein treated group D as 212.6±23.43 grams. A significant increase in blood glucose levels 182.07±10.63 mg/dl was noted in the Diabetic control (Group B) compared to Diacerein treated group C (110.13± 8.54 mg/dl) and group D (85.87±8.41 mg/dl) (P=0.001). HbA1c was markedly raised in the Group B- diabetic controls, while diacerein treated diabetic rats (groups C and D) showed a significant decrease in HbA1c (P=0.001). Conclusion: It was concluded that Diacerein achieves the Euglycemic state by reducing the levels of blood glucose and glycated hemoglobin (HbA1c) in Alloxan-Induced diabetes mellitus in Wistar Albino Rats
ABSTRACT
Aim:Ibuprofen is analgesic, antipyretic and anti-inflammatory drug, which is widely used as a cheap over-the counter drug(OTC); however, this drug accompanies anti coagulation/anti platelets effects which sometimes might illicit adverse effects. In this study, we investigated effect of ibuprofen on prothrombin time (PT), activated partial thromboplastin time (aPTT) and platelet count using wistar albino rats.Methods:A total of 21 rats grouped into 3(control, acute and chronic exposure groups, with all consisting of 7rats each) was used. The acute and chronic exposure group were given 0.7mg of ibuprofen orally for 1 and 21 days, respectively. Blood sample was collected via cardiac puncture thenanalyzed.Results:PT was significantly higher in both group 2 and 3 (acute and chronic exposure, respectively)than that of the control. Acute exposure group showed the highest PT rise.A PTT was not significantly different between group 2 and 3 versus the control group. Platelet count was significantly lower in both group 2 and 3than that in the control group (p<0.05). Group 3 (chronic exposure) showed the lowest platelet count.Conclusion:Oral administration of ibuprofen affected coagulation parameters and a longer exposure reduce platelets count. A strictly prescription for this drug may be needed to prevent its indiscriminate use

ABSTRACT
Introduction: The commonest day to day ailment of humanbeings is the gastrointestinal diseases. Apart from traditionaluses, there are several reports on important pharmacologicalactions of musa sapientum. Study aimed to compare acidsecretion and ulcer healing effect of methanolic extract ofbanana, ranitidine, and omeprazole.Material and methods: The present study was carried out on30 albino rats for a period of 7 days. The animals were dividedrandomly into 5 groups of 6 animals each. Group I or controlgroup received 3% gum acacia suspension orally for 7 days.Group II, III, IV and V received 100mg/kg of aspirin orally asa single dose the 7th day. Group III was pretreated with 100mg/kg of MSE orally for 7 days. Group IV was pretreated with 20mg/kg omeprazole and Group V was pretreated with 150mg/kg of ranitidine orally for 7 days. After the administration ofthe drugs on the 7th Day, the albino rats were fasted for 24 hrsand then sacrificed after 4 hrs of pyloric ligation.Results: In the control group (n=6) the values of ulcer index(µmol tyrosin/ml), free acidity (mEq/l), total acidity (mEq/l),and volume of gastric juice (ml/4 hrs) were 0.22±0.01,53.25±2.59, 72.24±4.19 and 5.1±0.32 respectively. Whencompared to aspirin treated group, the MSE pretreated group(100 mg/kg) single dose orally on 7th day showed significantreduction (p<0.01, n=6) of ulcer index, free and total acidity(mEq/l), and volume of gastric juice (ml/4 hrs), whosevalues were 5.3±0.46, 71.31±4.15, 72.24±4.19 and 65.4±2.9respectively.Conclusion: The present study suggests that themethanolic extract of musa sapientum possesses significantulceroprotective effect, which is comparable to omeprazoleand ranitidine, except for gastric juice, where the effect ofomeprazole was more. The observations of the present studyputs forward omeprazole as a promising ulceroprotectiveagent, but further studies with more refined extracts andtechniques on animal and human subjects are requiredto establish the true potential in terms of therapeutic andeconomic viability of this herbal plant.
ABSTRACT
Background: To produce peritonitis experimentally in albino rats by creation of a necrotic loop of terminal Ileum. Study of peritonitis and gross changes in peritoniteal cavity and to study the effect of single dose heparin (Anticoagulant) in experimentally produced peritonitis. Also to study and compare the effect of repeated small dosage of heparin in peritonitis. Material and MethodsThe rats were divided into 6 groups, under the 2 experiments. So each group comprised of 8 rats. The peritonitis was proceduced by Rasto's method, in which the peritonitis was caused by a gangrenous loop of small intestine . two types of experiment were carried out:1. Experiment 1 : The gangrenous loop which produced peritonitis was excised after 24 hours, normal saline was given in control group,whereas heparin as a single dose and heparin in small repeated dose were given by sub-cutaneous or intra-peritoneal route for 3 days. No abdominal toilet or antibiotics were given during the time. The surviving as well as the dead rats during observation period were subjected to laparotomy and detailed pathology of peritoneum was studied. 2. Experiment 2 : In this group the gangrenous loop was not resected after 24 hours and normal saline was given in control group 0.2 ml., or heparin in a single dose 50 I.U. or heparin in small repeated dose 20 I.U. twice a day for three days.All the rats were continuously observed during the post-operative period for evidence of any complications. Results:The peritonitis produced by a necrotic bowel loop was severe & brino-purulent.The formation of inter-mesentric abscess in control group was much more evident than the heparinised rats. The size of inter-mesentric abscess was smaller in treated group of albino rats than in control.The incidence of adhesion formation was much more in control group, than in the heparin group, the adhesion were very less friable and easily breakable. The survival rate in heparin treatment group was 75% to 87.5% as compared to the control group, where the survival rate was 50% only.The mortality in the control group, where the necrotic loop, was not resected was as high as 87.5% and rats died within 8 days after operation whereas the mortality rate in treatment group was low that is, from 50% to 60% only.Conclusion: By comparison and contrast of the results of the difference treatment group, it become evident that survival in the treated group was signicantly better than control group. About the evidence of intra-peritoneal infection, it shows that in treated group clearance of peritonitis was much faster than the control group of albino rats:The number and size of intramesentric abscesses were also smaller in treated group. There was also a little benecial effect on adhesion in heparinised albino rats as compared to control group.So heparin in small repeated doses has denitely a signicant effect on secondary bacterial peritonitis and its subsequent results.
ABSTRACT
Background: The use of liquid vaporizers as residential insecticides to control the problem of mosquito bites and to prevent adult, newborns and children from deadly vector borne diseases like Malaria, Dengue and chikungunya etc. is ever increasing. These products contain pyrethroid and emit parallethrin vapours when put to use at home. There are numerous side effects of these vapours like allergic sinusitis, difficulty in respiration, sleep disturbance, giddiness, headache, body ache and lethargy but the market for these product decides the outcome of all the research concerned with its safety. Histological studies can establish their toxic effects on Spinal Cord, cervical and lumbar enlargements in the White and Grey matter that forms structural continuity with the CNS. Accordingly the present study was planned to assess the safety of pyrethroid based mosquito repellent inhalational use and the histological insult to the spinal cord of Albino rats. Methods: Total of twenty albino rats were equally divided into control and experimental group. The experimental group was exposed to 3.2% w/v prallethrin vapours for total of 12 hours per day for 180 days. The control group rats was exposed to identical situation but without any exposure. The albino rats were sacrificed after the study period of exposure of 180 days. Spinal cord dissected., tissue processed, sectioned and stained with haematoxylin, eosin and thionin. Results: Grey matter of the spinal cord at cervical and lumbar enlargement showed numerous vacuoles with lightly stained cell body of neurons and Nissl’s dissolution with occasional inflammatory cells. Conclusions: Neurohistological study, inhalational route, neurotoxicity, adult albino rats, prallethrin vapours, spinal cord.
ABSTRACT
Background: Wound treatment still a task for medical professionals, according to the time advancement. We need to elaborate further new interventions to cope up this common factor of community.

Data obtained were analyzed by SPSS version 20 by applying One Way ANOVA and post hoc Tukey’s test.Conclusions: The results were shown potent anti-inflammatory effects of Lactobacillus acidophilus group in comparison with other conventional therapy. The study concludes that the topical application of Lactobacillus acidophilus had remarkable anti-inflammatory effects in wound management.
ABSTRACT
Background: Blood clotting is a process which prevents blood loss during injuries. Blood clots even when it is coming out from the blood vessels. Aloe vera is a perennial plant found all over India. It is commonly used in traditional system of medicine for treatment of wound healing, mouth ulcers, constipation, skin wrinkles and diabetes mellitus It is also used as antioxidant and antimicrobial agent. As it is used in traditional system of medicine for wound healing, this study was under taken to test the possible haemostatic effect of aloe vera.Methods: 12 rats were divided into two groups (control and test) with 6 rats in each group. Determination of Bleeding Time (BT), rat tail was warmed for one minute in water at 40?C and then dried. A small cut was made in the middle of the tail with a scalpel. In test group, a drop of aloe vera leaf extract was applied on the injured area immediately after making the cut in the middle of the tail, where as in the control group nothing was applied, and BT estimated. Determination of Clotting Time (CT), 12 test tubes were arranged in water bath at 37?C. Control Group: 0.4 ml of blood was collected from each rat in the control group and added to 6 test tubes kept in the water bath. Test group: For the remaining 6 test tubes 0.1 ml of aloe vera leaf extract was added. 0.4 ml of blood collected from the test group was added to these test tubes. The CT was estimated for both control group and test group.Results: The results were statistically analyzed by using unpaired t-test. The reduction in BT and CT for test group was statistically highly significant (p<0.001) compared to control group.Conclusions: In this study aloe vera leaf extract significantly reduced both BT and CT in the test group.
ABSTRACT
Background: Pain and pyrexia are the warning signals, primarily protective in nature, that cause discomfort and suffering and may even be unbearable and incapacitating. The modern drugs (like opioids, NSAIDs, corticosteroids) currently used for the management of pain, fever and inflammatory conditions, present with many known adverse effects. Tinospora cordifolia known as Giloe, widely used in folk medicine due to its property to cure a number of diseases. Hence the present study was undertaken to explore the analgesic activity of water-soluble extract of stem of T. cordifolia in albino rats in experimentally induced pain.Methods: Present study was done in the department of pharmacology, albino rats were used to study the analgesic activity of T. cordifolia aqueous extract at the dose of 1.25g/kg,2.5g/kg and 5g/kg p.o. Various methods like Eddy’s hot plate, tail flick test and acetic acid induced writhing were used for the anti- nociceptive study.Results: In Eddy’s hot plate and tail flick test an increase in reaction time was observed with peak effect at 90min. Results were similar to the standard drug Tramadol in acetic acid induced writhing increase in time of onset, decrease in number and duration of writhing was observed.Conclusions: Aqueous extract of T. cordifolia was effective in all the three models of pain suggesting its possible action by central and peripheral mechanisms. Activity of T. cordifolia can be attributed to various phytoconstituents viz. protoberberine alkaloids, terpenoids, glycosides and polysaccharides. It can be developed as potent analgesic agent in future.
ABSTRACT
Bacterial cellulose (BC) is a natural polymer that can be utilized for many applications. Because of its renewable nature, goodbiocompatibility and excellent physical features of bacterial cellulose, it can be utilized in pharmaceutical, biomedical fields, andnanotechnology applications. In this study, we prepared antibiotic bacterial cellulose loaded with tetracycline hydrochloride andgentamicin, and its drug release, as well as antibacterial activity, were evaluated separately. The structure and morphology of the loadedbacterial cellulose were determined by scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR).AATCC100 test was used for antibacterial properties against Escherichia coli and Staphylococcus aureus. Ultraviolet spectrophotometrydevice was used to detect absorption and release process of mentioned antibacterial cellulose. By these unique specifications of bacterialcellulose layer loaded with tetracycline hydrochloride and gentamicin, we found that they may successfully serve as a wound dressing andother medical biomaterials.
ABSTRACT
This study was designed to evaluate the effect of a daily dose of tramadol on selected biomarkers viz: haematological parameters, sperm count, kidney and liver damage in male albino rats. Twenty four wistar rats were divided randomly into two groups: control group and treated groups, the treated group were further divided into four groups and housed in cages. Clean drinking water was served to control (group 1), and 1.6 mg/kg bodyweight of tramadol was administered to group 2 (7 days treatment), group 3 (14 days treatment), group 4 (21 days treatment) and group 5 (21 days treatment +7 days withdrawal) in addition to a daily standard diet for all groups. Treatment of rats with tramadol caused significant decrease (P<0.05) in WBC, platelet and lymph. in group 2, on bicarbonate, AST and protein, it showed significant decrease (P<0.05) in group 3, and it showed significant decrease (P<0.05) in group 5 on Cl-, AST, ALT, bicarbonate, AST, PCV, Hb, RBC, WBC, platelet, lymphocytes and sperm count. The results indicates that tramadol has negative effects on the liver which may induce severe liver damage when used for a prolonged period, the results also shows that tramadol can cause anaemia as seen by the observed negative changes in the blood parameters evaluated. Therefore, administration should be with great caution and from a licensed pharmacist or doctor while self prescription or over the counter administration should be avoided considering the associated adverse effects.

Aqueous extract of Psidium guajava leaves showed significant antidepressant activity. Both Psidium guajava aqueous extract (PGAE)-100mg/kg and 200mg/kg showed antidepressant effect but compared to 100mg/kg dose of PGAE, 200mg/kg showed significant antidepressant activity.Conclusions: From this study it can be concluded that aqueous extract of Psidium guajava leaves has antidepressant activity.
ABSTRACT
Background: Calcium channel blockers are being used in the treatment of hypertension, ischemic heart disease, cardiac arrhythmias etc. They act by blocking the slow calcium channels. Influx of calcium is an essential step in the release of histamine and 5HT from mast cells and in the synthesis and release of prostaglandins. They are the main mediators in the process of inflammation. The aim of the present study was to compare anti-inflammatory properties of calcium channel blockers and aspirin in albino rats.Methods: Present study was prospective intervention study carried out to compare anti-inflammatory properties of calcium channel blockers and aspirin in albino rats. Total 30 albino rats were used, and they were divided into 5 groups of 6 each. First group of rats was control group where normal saline was used. Second group was standard group where aspirin was used. Remaining three groups were test groups and given nifedipine, amlodipine and diltiazem respectively. Effects were observed and compared between the groups.Results: In carrageenan method, the anti-inflammatory response of Aspirin was significantly higher. Nifedipine response was <aspirin but >diltiazem. The response of amlodipine was not significantly > that of control percent inhibition. In histamine method, the anti-inflammatory response of aspirin was significantly highest. Anti-inflammatory response of nifedipine was < aspirin but > diltiazem. Diltiazem response was < nifedipine but > amlodipine. In formaldehyde method, aspirin inhibition was highest at 96.2% followed by nifedipine (90.7%), diltiazem (75.9%) and amlodipine (3.7%). In cotton wool pellet granuloma, the mean dry granuloma weight was least for aspirin and percent anti-inflammatory activity was significantly high.Conclusions: Calcium channel blockers (nifedipine, diltiazem) have shown comparable anti-inflammatory property with that of aspirin. Further clinical studies are required for confirmation.
ABSTRACT
Background: Global burden of disease statistics indicate that 4 of 10 most important causes of disease worldwide are psychiatric in origin. Anxiety affects 1/8th of total population of the world and is a very important area of research interest in psychopharmacology. Medicinal plants and plant products are the oldest tried health-care products. Their importance is growing not only in developing countries but in many developed countries. Curcuma amada Roxb. (CA) commonly known as Mango Ginger is a rhizomatous aromatic herb which is used in this country for culinary purposes and also to treat various diseases. The rhizomes of Curcuma amada was screened for anxiolytic activity and locomotor behavior in Wistar albino rats.Methods: Wistar albino rats were divided into three groups as control (Distilled water with 0.1% CMC), standard (Diazepam - 1mg/kg) and test - Ethanolic Extract of Curcuma amada Rhizome (EECAR-250 mg/kg). They were administered drugs orally for a period of 10 days, and screened for anxiolytic activity using Light dark arena model and Actophotometer for assessing the locomotor behavior on the 10th day. The number of crossings and time spent in light arena for anxiolytic activity, and the number of movements in Actophotometer was noted. Data was analyzed by one way ANOVA followed by Tukey Kramer multiple comparison test using GraphPad InStat software.Results: Curcuma amada (250mg/kg) showed increased time spent in light arena and decreased locomotor behavior which was statistically significant.Conclusions: Curcuma amada possesses significant anxiolytic with CNS depressant activity.
ABSTRACT
Background: Diabetes is almost growing health concern worldwide and now emerging as an epidemic world over. Recently, full attention is being paid to the study of natural products as potential antidiabetics. Objective of the study was to evaluate the antidiabetic effect of hydroalcoholic leaf extract of Annona squamosa (HAEAS) plant in alloxan monohydrate induced diabetic albino rats.Methods: Almost a 30 Albino rats with 150- 200 grams weight were weighed and grouped into 5 equal groups taking 6 rats in every group. Group A served as normal control, Group B as diabetic control, received alloxan monnohydrate. Group C and D was received alloxan + HAEAS suspension at 350 and 700 mg/kg doses orally respectively, Group E was given alloxan + standard drug (Glibenclamide 5mg/kg) suspension for 28 successive days and the effect of HAEAS on blood sugar(BS) levels was measured at regular intervals. At the end portion of this investigational research study samples of blood were collected from all rats on 0day (initial), after 72 hrs and after 28th day (29thday) of given test drug HAEAS treatment for biochemical estimation of BS and the BS values were observed.Results: The present research study revealed that HAEAS leaves has antidiabetic effect against alloxan monohydrate induced diabetic rats on i.p. alloxan injection at 150mg/kg.b.w. and confirms that on i.p. alloxan injection causes a significant rise off BS in untreated albino rats when compared to control group. Diabetic rats treatment with HAEAS leaves for 28 days caused dose a dependent fall in BS values. Glibenclamide treated diabetic rats also showed a significant (P <0.00) fall in BS content after 28 days of treatment.Conclusions: This research study confirms that HAEAS leaves has shown significant antidiabetic effect at 350 and 700 mg/kg. b.w. doses in alloxan monohydrate induced diabetic rats.
ABSTRACT
Background: Individuals with epilepsy have a higher incidence of psychiatric disorders than person without epilepsy. Epidemiological studies have shown that the co-morbidity of epilepsy and depression to be high as 50%. The conventional anti-depressants are believed to lower the seizure threshold making it difficult to treat the co-morbid depression, but animal studies have shown SSRIs, a common anti-depressant, to have anti-convulsant properties. So, we propose to study the anticonvulsant effects of fluoxetine, a SSRI, in albino rats against maximal electroshock seizure and to compare against a standard antiepileptic drug phenytoin.Methods: The anticonvulsant effect of fluoxetine was observed in model of maximal electroconvulsive seizure threshold in albino rats. The animals were divided into 3 groups having 6 animals each, receiving distilled water, fluoxetine and phenytoin respectively. The drugs were given orally, and the effect was observed on day 7, 14 and 21. Tonic hind-limb extension was taken as the parameter of electroshock seizure. The effects were compared against a standard anti-seizure drug phenytoin.Results: Fluoxetine showed significant elevation of the seizure threshold following 14 days of administration (P value 0.031). The effect was comparable to phenytoin with no significant difference after 7, 14 and 21 days of treatment (P-value 0.485, 0.699 and 0.818 respectively) though phenytoin showed significant anti-seizure effect since day 7 of treatment.Conclusions: Fluoxetine showed significant anti-seizure activity against electroconvulsive seizure in albino rats.
