Pethidine induced changes in ovarian follicular kinetics and biochemical parameters in albino rats

Patil, Somanath Reddy,Patil, Saraswati B,Malashetty, Vijaykumar B Kyung Hee Oriental Medicine Research Center 2006 Oriental pharmacy and experimental medicine Vol.6 No.4

Pethidine at the dose level of 0.5 mg and 0.75 mg/100 g body weight administered for 20 days to the cycling albino rats caused decrease in the ovarian weight and its protein content. The ovarian folliculogenesis in treated rats is hampered; as a result the follicles which are at the different stages of growth underwent regression. Therefore, the number of healthy follicles is reduced and atretic follicles increased. The elevated levels of ovarian cholesterol and decreased level of glycogen in the pethidine treated rats indicates the inhibition brought in steroidogenesis, which is dependent on pituitary gonadotrophins.

Antispermatogenic and antiandrogenic activities of various extracts of Melia azedarach Linn. seeds in albino rats

Patil, Sharanabasappa A.,Malashetty, Vijaykumar B.,Patil, Saraswati B. Kyung Hee Oriental Medicine Research Center 2003 Oriental pharmacy and experimental medicine Vol.3 No.3

Petroleum ether, chloroform and ethanol extracts of the seeds of Melia azedarach Linn. administered orally to male rats at the dose level of 25 mg/100 g body weight for 48 days showed antispermatogenic activity, as the number of spermatocytes, spermatids and spermatozoa was decreased. The total cholesterol content was increased while protein and glycogen contents were decreased. The acid phosphatase content was also decreased while that of alkaline phosphatase increased. At the same time the weight of caput and cauda epididymis, prostate gland, seminal vesicle and Levator Ani muscle was decreased indicating its antiandrogenic property. Of the three extracts, the petroleum ether extract was more potent in its antispermatogenic and antiandrogenic activities and did not produce any sings of toxicity upto a dose of 25 mg/100 g body weight oral administration. After subjecting it to preliminary phytochemical screening the petroleum ether extract showed positive tests for steroids and saponins.

Monocrotophos induced inhibition of the activities of testis and accessory reproductive organs in male mice

Patill, Saraswati B,Malashetty, Vijaykumar B Kyung Hee Oriental Medicine Research Center 2007 Oriental pharmacy and experimental medicine Vol.7 No.3

Monocrotophos was administered orally to adult male albino mice at dose level of 3.0 mg/kg body weight/day/mice for 50 days. The treatment has found to affect spermatogenesis as well as the endocrine functions of the testis as indicated by gravimetric, histopathological and biochemical changes. The treatment has caused degenerative changes in the seminiferous tubules and Leydig cells of the testis and regression of the epididymis, seminal vesicle, vas deferens, prostate, Cowper's gland and levator ani. Similarly, cauda epididymal sperm count and sperm motility have shown significant reduction. There was a significant reduction in the protein, glycogen, sialic acid, acid and alkaline phosphatase and increase in cholesterol in the testis of monocrotophos treated mice compared with the control. The causative factors for these changes due to monocrotophos administration were discussed.

Spermatogenic index and hormonal profile in the rats received chromatographic fractions of ethanol extract of Crotalaria juncea L. seeds

Malashetty, Vijaykumar B.,Patil, Saraswati B. Kyung Hee Oriental Medicine Research Center 2006 Oriental pharmacy and experimental medicine Vol.6 No.2

The ethanol extract of the Crotalaria juncea seeds, which showed promising antispermatogenic and antiandrogenic activities in albino mice, was taken up further for the isolation of the active fractions present in it. Two fractions that were obtained from thin layer chromatography were subjected for testing to know their antispermatogenic and antiandrogenic activities. After preliminary trials the fraction I showed maximum antifertility activity at the dose level of 200 mg/kg body weight when administered orally to the rats for 50 days. The fraction I was found to affect spermatogenesis as well as the endocrine functions of the testis as indicated by gravimetric, histopathological and biochemical changes. Further this fraction has caused degenerative changes in the seminiferous tubules and Leydig cells of the testis. The accessory reproductive organs like epididymis, seminal vesicles, vas deferens, prostrate, Cowper's gland and Levator Ani muscle showed significant malfunction. Cauda epididymal sperm count and sperm motility were reduced significantly. The treatment has also resulted in increase in the cholesterol level and alkaline phosphatase activity, and decrease in protein, glycogen, sialic acid contents and acid phosphatase activity in testis. It is noteworthy that RIA studies have shown significant reduction in serum FSH, LH and testosterone. Scanning electron microscopic observations revealed abnormalities in sperm structure.

Ramesh L Londonkar,Sharangouda,Saraswati B Patil 경희대학교 융합한의과학연구소 2008 Oriental Pharmacy and Experimental Medicine Vol.8 No.1

Adult male albino rats were treated with 0.5 mg and 0.75 mg morphine/100 g body weight intraperitoneally for 30 days. All the animals were autopsied on 31st day. Epididymis and vas deferens were dissected out, weighed and processed for histological and biochemical studies. Morphine has caused a reduction in the weight of epididymis and vas deferens in both the doses of drug treated groups. The total cholesterol content is increased while protein, DNA and RNA contents and epididymal sperm counts are decreased. The acid phosphatase content is decreased 10.12 ± 0.11 in caput, 9.26 ± 0.30 in cauda of epididymis and in vas deferens 8.14 ± 0.15 in 0.5 mg treated groups and in 0.75 mg treated rats shows 9.52 ± 0.27 in caput, 9.14 ± 0.18 in cauda of epididymis and in vas deferens 7.84 ± 0.11is decreased, whereas alkaline phosphatase is increased. The surface epithelial cell height of these ducts is reduced and secretory activity is inhibited with the disruption of epithelial cell projections. The gravimetric and histometric changes of epididymis and vas deferens may be due to non-availability of androgens in morphine treated rats.

Pateel, Mallikarjun,Sharanabasappa, Sharanabasappa,Malashetty, Viajykumar B,Patil, Saraswati B,A, Veeranagoud Kyung Hee Oriental Medicine Research Center 2005 Oriental pharmacy and experimental medicine Vol.5 No.4

In the present investigation twelve indigenous medicinal plants have been screened for their antiimplantation activity in albino rats. The plant material was subjected for soxhlation successively and separately from non-polar solvents to polar solvents i.e., petroleum ether benzene and ethanol. Out of these three extracts the petroleum ether extract of seeds of Citrus medica, aerial part of Oxalis corniculata and Tinospora cardifolia have showed maximum antiimplantation activity. Ethanol extract of leaves of Cardiospermum helicacabum, roots of Echinops echinatus, leaves of Melia azedarach, seeds of Momordica charantia and bark of Terminalia bellirica have shown maximum antiimplantation activity amongst the three extracts of each plant material screened. Though all the three extracts of seeds of Annona squamosa and leaves of Zizyphus jujube screened for antiimplantation activity, no extract has showed any loss in implantation. The details of the results obtained are discussed.

Effect of Crotalaria juncea seed extracts on the estrous cycle and ovarian activity in albino mice

Malashetty, Vijaykumar B.,I., Sangamma,A., Sharanabasappa,Patil, Saraswati B. Kyung Hee Oriental Medicine Research Center 2004 Oriental pharmacy and experimental medicine Vol.4 No.2

Petroleum ether, benzene and alcohol extracts of seeds of C. juncea administered orally at the dose level of 25mg/100g body weight to adult female mice for 30 days, resulted in irregular estrous cycle with prolonged estrus and metaestrus and reduced diestrus and proestrus during the experimental period. Histological studies of the ovary indicate increases in the number of atretic follicles but decreases in the number of developing follicles, Graafian follicles and corpora lutea. The total cholesterol content of the ovary is increased, whereas ascorbic acid content is decreased. The weight of the uterus and its micrometric measurement in all experimental mice are increased significantly. The alcoholic extracts showed estrogenic activity in immature mice by early opening of the vagina, premature cornification of the vaginal epithilium and increases in uterine weight. However, alcohol extract of seeds of C. juncea was more effective in causing these changes compared to other extracts. After subjecting to preliminary phytochemical screenings alcohol extract showed positive; test for alkaloids, steroids, glycosides, flavones, phenols and tannins.

Post-coital antiimplantation and pregnancy interruption potency of the seeds of Crotalaria juncea Linn

Malashetty, Vijaykumar B.,A., Sharanabasappa,Patil, Saraswati B. Kyung Hee Oriental Medicine Research Center 2004 Oriental pharmacy and experimental medicine Vol.4 No.2

Petroleum ether, benzene and alcohol extracts of the seeds of C. juncea were tested for antiimplantation and pregnancy interruption activities in female albino rats. Of these three extracts, the alcohol extract was found to be the most effective in causing antiimplantation and pregnancy interruption activities. These adverse effects on fertility are reversible upon withdrawal of the extract treatments. The alcohol extract was found to possess estrogenic activity. After subjecting to preliminary phytochemical screening, the alcohol extract showed positive tests for alkaloids, steroids, glycosides, saponins, flavonoides, fixed oils, phenols and tannins.
