The present study was carried out to investigate the effect of arsenic trioxide on the DNA and histomorphology of testis, liver and kidney of Swiss albino mice, Mus musculus. Oral administration of arsenic trioxide induced DNA damage in the testis, liver and kidney marked by light pink staining of nuclei after Feulgen’s reaction with reduced fine chromatin. Simultaneously severe histological changes were noted like distortion of seminiferous tubules, disorganization of spermatogonia, spermatocytes and spermatids with cytoplasmic vacuolization and nuclear pycnosis in testis. There was almost disappearance of sinusoids due to disruption of hepatic plates, inflammatory cellular infiltration around central veins and cytoplasmic vacuolization in hepatocytes with large irregular nuclei in liver of treated mice. Disorganized glomeruli with distorted Bowman’s capsules and mild to severe multifocal cloudy and hydropic degeneration with necrosis of tubules were observed in the kidney of treated mice. Inference drawn from the study indicated that arsenic induced both genotoxic histotoxic lesions.

The results on the effect of oral administration of cadmium chloride on the histomorphology of the stomach and small intestine of Swiss albino mice revealed severe histopathological effects in the tissues of both stomach and small intestine. There is marked atrophy of musculature, and disintegration of sub-mucosal and mucosal tissues, distortion of villi with disintegration of mucosal epithelial cells characterized by cytoplasmic vacuolization, nuclear pycnosis and nuclear fragmentation. A significant damage in the Brunner’s gland and crypts of Liberkuhn has been observed.

Different Doses

The aim of this study was to investigate the dose-related effects of fenitrothion (FNT) on the liver and kidney. The study was conducted on 8-week-old male Wistar rats that were divided into four groups (three experimental groups and one control group) and were treated orally with different doses (25, 50, 100 mg/kg) of FNT for 28 consecutive days. After treatment, the rats were anesthetized with ether and liver and kidney samples were taken for histological studies. The results showed that the histopathological changes in the liver were mainly represented by parenchymatous degeneration of hepatocytes with mild necrosis, leukocytic infiltration in the portal area, severe congestion, and hemorrhage. These changes were dose dependent. Marked tubular dilation, hydropic degeneration in tubular epithelium, moderate congestion, and hemorrhage in the cortical and medulla part of the kidney were recorded. Histopathologic examination of the liver and kidney indicated a significant injury only in rats receiving 100 mg/kg FNT.

Histological Result

The present paper deals with the effect of polymeric compound poly (N-isopropyl acrylamide) “PNIPAM” for their toxicity on hepatic cells. The nanoparticle is a xenobiotic compound that accumulates in the liver for their metabolism. Non-metabolizing xenobiotic compounds such as PNIPAM produces anomalies in the hepatic cells. Certain enzymes such as ALT and ALP can be assayed for the hepatocytic toxicity.An attempt has been made to know the toxic effect of “PNIPAM” in a concentration of 0.8mg/ml on the hepatic cells of Swiss Albino mice, Mus musculus. The ALT and ALP analysis were performed through test kits for their quantitative estimation. The histological result shows that several lesions were produced after the introduction of aqueous solution of PNIPAM for an incubation period of 48 hours. The toxicity was confirmed Spectrophotometrically by the assessment of enzyme ALT and ALP. The increased concentration of ALT (55.0 IU/L) and slight decrease in ALP (40.0 IU/L) concentration was responsible for the metabolic alteration and production of hepatocytic anomalies in the mice.DOI: http://dx.doi.org/10.3126/ijasbt.v1i4.9104    Int J Appl Sci Biotechnol, Vol. 1(4): 208-213

Population explosion is a major problem it is raising tremendously; this may affect drastically the economic growth. So family planning has been promoted through several methods of contraception. A wide variety of synthetic contraceptive agents are available, but these cannot be used continuously due to their side effects. Thus the present study was to evaluate the effect of Bougainvillea spectabilis on fertility of male and female mice. Swiss Albino mice were orally administered with aqueous crude extract of the leaves of Bougainvillea spectabilis (800 mg/kg of body weight/day, for 30 days), and effect of crude extract on reproductive organs and fertility was investigated. The treatment Caused decrease in weight of testis, sperm count and the histological examination revealed a reduction in the size of seminiferous tubules along with the thickness of germinal epithelial cells, though some of the epithelial cells and interstitial cells of leydig showed hypertrophy. Moreover, the lumen of the tubules was found to be devoid of sperms. On the other hand, in treated females no histological changes could be observed. The only marked change, which could be visualized, was the slight disruption of estrous cycle having prolonged metaestrus phase, which has been increased by 145.28 %. The overall duration of estrous cycle had been extended by more than one day. The hormonal profile was also influenced by the Bougainvillea spectabilis extract. The testosterone and estrogen levels were significantly decreased.
