Evaluation of nephroprotective and nephrocurative activity of Aegle marmelos on albino rats using experimental model

Background: Renal diseases are common now days because of multiple nephrotoxic drugs use like aminoglycosides, analgesic etc. Many diseases like Diabetes and Hypertension also contributing to renal diseases. One of the mechanisms for nephrotoxicity is production of free radicals. The phytochemicals obtained from some plants are claimed to be useful in prevention of nephrotoxicity. One of the good sources of these phytochemicals is leaves of Aegle marmelos (Bael) which has antioxidant property that can be useful in nephroprotection. Hence this study was designed to investigate the nephroprotective as well as nephrocurative potential of Aegle marmelos.Methods: Study was done on albino rats at LLRM Medical College as per CPCSEA guidelines after obtaining permission from IAEC. Nephrotoxicity was induced using injection gentamicin(40mg/kg). The nephroprotective and nephrocurative effect was quantified using serum markers (BUN, Serum creatinine) and histopathological changes. Statistical analysis was done using ANOVA followed by post hoc dunnet’s test.Results: When compared with gentamicin induced nephrotoxicity, rats those who received aqueous extract of Aegle marmelos leaves showed significant (p<.001) reduction in nephrotoxicity.Conclusions: It can be concluded from this study that leaves of Aegle marmelos possess siginificant nephroprotective activity.

Evaluation of Cardioprotective activity of Asparagus racemosus against Doxorubicin induced cardiotoxicity in albino rats: an experimental study

Background: Cardiotoxicity is one of the most feared side effects of anticancer agents like Doxorubicin. Asparagus racemosus is a widely used medicinal plant in Indian system of medicine known for its antioxidant activity. In certain studies ethanol extract of Asparagus racemosus has shown to possess cardioprotective activity in experimental animals while in some other studies cardioprotective potential of Asparagus racemosus has not been demonstrated. Therefore, due to the controversial action, the present study was designed to explore the cardioprotective effect of aqueous effect of Asparagus racemosus against doxorubicin induced cardiotoxity.Methods: Following approval from Institutional Animal Ethics Committee of L.L.R.M Medical College registered under CPCSEA, India, this study was conducted in which 30 rats were randomized into five groups of six rats each. Group I received 2 ml/kg b.w. normal saline p.o for 21 days, group II apart from receiving pellet diet and normal saline for 21 days were treated with Doxorubicin in a single dose of 20 mg/kg intraperitoneally on the 21st day, group III and group IV received aqueous extract of Asparagus racemosus in doses of 250 mg/kg/day and 500 mg/kg/day respectively p.o. for 21 days followed by administration of Doxorubicin (20 mg/kg i.p.) on the 21st day, Group V received Carvedilol in doses of  30 mg/kg/day p.o. for 21 days followed by administration of Doxorubicin (20mg/kg i.p) on the 21st day. Then they were anaesthetized and blood sample was collected from abdominal aorta for performing blood test i.e. Creatinine kinase MB fraction (CK-MB), Lactate dehydrogenase (LDH), Serum glutamate oxaloacetate transaminase (SGOT), Serum glutamate pyruvate transaminase (SGPT). After blood collection the animals were sacrificed and heart was dissected out for histopathological study. The data obtained was organized and analysed by suitable statistical methods i.e. ANOVA followed by Post Hoc test.Results: CK-MB, LDH, SGOT and SGPT levels were found to be significantly raised (p<0.001) in Doxorubicin treated group. Asparagus racemosus pretreated groups exhibited significant limitation (p<0.001) in rise in levels of CK-MB,LDH,SGOT and SGPT levels in a dose dependent manner following Doxorubicin administration which were comparable to the group treated with the standard cardioprotective drug Carvedilol. Histopathological changes further corroborated cardioprotective potential of Asparagus racemosus.Conclusions: The present study concluded that aqueous extract of Asparagus racemosus possess cardioprotective potential against Doxorubicin induced cardiotoxicity

Tinospora cordifolia is an Indian medicinal plant, widely used because of its antioxidant activity. Due to limited scientific literature exploring its nephroprotective potential, the present study was designed to investigate the nephroprotective effect of aqueous extract of Tinospora cordifolia against gentamicin induced nephrotoxicity in albino rats.Methods: The study was commenced following approval from Institutional Animal Ethical Committee of L.L.R.M. Medical College, Meerut (UP). Twenty four rats were randomised into four groups of six animals each. Total duration of study was 21 days. Group I received normal saline p.o., group II received normal saline along with gentamicin on last 5 days, group III and IV received Tinospora cordifolia in graded doses p.o. along with gentamicin on last 5 days. Injection gentamicin (40mg/kg) i.p. was given once daily for last 5 days to induce nephrotoxicity in rats of groups II, III and IV. The rats were sacrificed under anaesthesia, blood samples analysed for blood urea nitrogen (BUN) and serum creatinine levels and histopathological changes were studied. Statistical analysis was done using ANOVA followed by post hoc test.Results: Tinospora cordifolia pre-treated groups exhibited significant (p<0.001) limitation in rise in levels of BUN and serum creatinine in a dose dependent manner. Histolopathological observations further corroborated the biochemical findings.Conclusions: The present study concluded that aqueous extract of Tinospora cordifolia possesses nephroprotective potential against gentamicin induced nephrotoxicity

Evaluation of nephroprotective and nephrocurative activity of Solanum nigrum on gentamicin induced nephrotoxicity in experimental rats

Background: Aminoglycoside antibiotics are most commonly used drugs for the prevention and treatment of gram negative infections. Nephrotoxicity is the main side effect that restricts its long duration use. Modern medicines to treat nephrotoxicity are costly and also not vary effective. Solanum nigrum fruits, having potent antioxidant property can be used for nephroprotection as well as nephrocure.Methods: The study was carried out in two phases. Nephroprotective phase, 54 rats were randomized in 3 groups named G10, G20 & G30 according to 10, 20 & 30 days of treatment. Each group was randomized in three subgroups i.e. control C group [received normal saline (2 ml/100 gm/day) daily for test duration], GT group [received normal saline (2 ml/100 gm/day) daily for test duration & intra-peritoneal gentamicin (40mg/kg) for last five days] & SNT group [received orally S.nigrum (200 mg/kg/day) daily for the test duration and intra-peritoneal gentamicin (40 mg/kg) for last five days]. Rats were sacrificed 24 hours after the last dose of gentamicin (on 11th, 21st and 31st day). In nephrocurative phase, 72 rats were randomised in two groups of 36 rats each. Group-1 received intra-peritoneal gentamicin (40 mg/dl) for five days. Group-2 received intra-peritoneal gentamicin (40 mg/dl) for five days and then S.nigrum (200 mg/kg/day) orally till the rats are sacrificed. Six rats from each group were sacrificed on 3rd, 5th, 7th, 10th, 12th and 14th day after administration of last dose of gentamicin. Blood sample were taken for evaluation of BUN and serum creatinine.Results: There was significant decrease in BUN and serum creatinine values as compared to GT group in all test duration in phase-1. In phase two there was no significant difference of these markers in two groups.Conclusions: S.nigrum fruits extract provide nephroprotection against gentamicin induced nephrotoxicity

A comparative analysis of conventional smear and sure path liquid-based cytology with cell block preparation

Background: Cervical cancer is ranked as the most frequent cancer in women in India. Conventional papanicolaou smear has been the mainstay of cervical cancer screening since the 1960s. As an alternative liquid-based cytology (LBC) was introduced in the mid-1990s, which are found to increase cytologic detection of squamous intraepithelial lesions and a reduction in the number of unsatisfactory pap tests.Present study aims at comparison of liquid-based cytology with conventional cytology in detecting uterine cervical intraepithelial lesions.Methods: The present study was conducted in the department of pathology in collaboration with the department of obstetrics and gynecology, Pt. B.D. Sharma PGIMS Rohtak including 100 non-pregnant female patients coming in the outpatient department of obstetrics and gynecology. Both liquid based and conventional pap smears were examined under the microscope and reported according to the 2001 Bethesda system. Cell blocks were prepared sin all the cases from the residual material of LBC.Results: Median age was 42 years. More inadequate smears were reported on CS (17%) as compared to LBC (11%). In both, maximum number of cases reported were inflammatory. Equal number of cases were reported as SCC (n=4) in both.Conclusions: Liquid based cytology has been developed to address the sampling problems of conventional Pap smear. But because of the increased cost of LBC in terms of capital investment, operation and disposables, developing countries should carefully consider the potential benefits and drawbacks of LBC before adopting this new technology

Fungal endometritis in bovines

Fungus is well capable of producing reproductive failures in bovines. As fungus is an opportunistic pathogen, there are more chances for fungus to cause infection in the uterus when certain predisposing factors like prolonged intra-uterine antibiotic therapy, persistent endometritis, presence of necrotic foci, immunosuppression and pneumovagina are available. Various authors have reported incidence of fungal endometritis in repeat breeder endometritic cows and buffaloes. Uterine culture along with the cytological examination of the uterine secretions considered being best way to diagnose this condition, however endometrial biopsy can be used to access the efficacy of treatment to invasive yeast. Intra-uterine treatment with antiseptic solutions and Lugol’s iodine had been found effective in bovines
