The objective of present study to investigate the hepatoprotective activity of hydro-alcohollic extract leaves of Pterospermum acerifollium against antitubercular drug induced liver damage in swiss albino mice and also performs antimicrobial activity by disc diffusion assay. Successive extractions was performed with different organic solvents viz; hydroalcohollic by cold maceration. The extract was analysed as antioxidant activity as a content of Total phenolic content, Total flavanoid content, Reducing power assay and DPPH Scavenging assay. Antimicrobial activity of methanolic extract was estimated by Agar well diffusion method. Antitubercular drug induced is used as toxicants in hepatoprotective studies in acute condition was analysed by serum biochemical estimations by AST, ALT, ALP and Total Bilirubin. In-vivo Antioxidant activity was performed by LPO, GSH, SOD and Catalase. During the collection of tissue for biochemical estimation piece of tissue cut and transferred for Histopathological estimation. The levels were measured and it indicated that the extract had significant antioxidant activity however the results obtained were dose dependent the higher the dose (400 mg/kg) the better activity. The extract administered at dose 400 mg/kg showed better activity. The treatment with hydroalcohollic extract of Pterospermum acerifillium reduced the elevated levels of SGOT, SGPT, ALP, TB and also reversed the hepatic damage towards normal which further supports the hepatoprotective activity. Keywords: Succesive extraction, In-vivo, Serum biochemical, Cold maceration

Malaria is regarded as one of the most lethal diseases. Resistance to artemisinin and its derivatives jeopardises effective malaria treatment. Finding novel antimalarial chemicals is critical given the existing treatment situation. This work aimed to examine the antiplasmodial capabilities of <i>Pseudarthria hookeri</i> fractions and flavonoids in vivo. The fractions and compounds antiplasmodial activity were evaluated on male Swiss albino mice infected with <i>Plasmodium berghei</i>, and on healthy female Swiss albino mice, the crude extract's acute toxicity was assessed. The EtOAc fraction had significant antiplasmodial activity (32.53 percent suppression at 500 mg/kg BW) and considerably prolonged the survival period of infected mice (9.8 days) compared to control mice (7.8 days). Parasitaemia was dramatically reduced (85.01, 59.41, and 70.39 percent), and the mean survival time extended (11.33, 10.00, and 9.33 days) with 15, 20 and 35 mg/kg of quercetin (<b>1</b>), 7-O-benzyl-6-prenylpinocembrin (<b>6</b>) and 6,8-diprenyleriodictyol (<b>11</b>) (isolates of the EtOAc fraction), respectively. BW loss and PCV reduction were also averted. Moreover, at 2500 mg/kg, the crude extract of <i>P. hookeri</i> showed no acute toxicity in mice. LC-MS analysis of the EtOAc fraction enabled the identification of nine flavonoids, with <b>8</b> and <b>11</b> being the main components. The present investigation confirmed <i>P. hookeri</i>'s antiplasmodial action, substantiating its ethnomedicinal application for malaria treatment.

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.
