Polyphenol-rich extract of Ocimum gratissimum leaves prevented toxic effects of cyclophosphamide on the kidney function of Wistar rats.

Background: Cyclophosphamide (CP) is one of the potent and low cost chemotherapy used in clinical setting against a variety of tumors. However, its association with nephrotoxicity limits its therapeutic use. Ocimum gratissimum leaf is a medicinal plant with numerous pharmacological and therapeutic efficacies, such as antioxidant, anti-inflammation, and anti-apoptotic properties.

Willingness of Family Caregivers to Consent to Relative's Postmortem Examination that Die Suddenly in a Nigerian Tertiary Hospital.

Background: Postmortem examination is necessary to diagnose the cause of sudden death, and family caregivers are expected to consent to this examination. This study assessed knowledge, attitude, practices and willingness of family caregivers to consent to postmortem examination of their relative if they die suddenly in a Nigerian tertiary hospital.

Methods: Descriptive cross-sectional study of family caregivers of our patients that completed an interviewer administered semistructured questionnaire assessing their knowledge, attitude, practices and willingness to consent to postmortem examination of their relative if they die suddenly.

Barium chloride dose-dependently induced heart and lung injury in Wistar rats.

Barium (Ba) is one of the environmental pollutant metals that incite deleterious effects on human health. The present study investigated the effects of exposure to different doses of barium chloride (BaCl ) on heart and lung of Wistar rats. Rats were exposed to BaCl at 150, 300, and 600 mg/L for seven consecutive days.

Protective Effects of Methanol Extract of (.) Leaf on Aspirin-Induced Gastric Ulceration and Oxidative Mucosal Damage in a Rat Model of Gastric Injury.

This study investigated the quantitative polyphenolic constituents and gastroprotective effects of methanol extract of leaf (MEVA) against aspirin-induced gastric ulcer in rats. Ulceration was induced by 3 days' oral administration of aspirin (150 mg/kg body weight). Wistar rats were pretreated with cimetidine (reference drug) at a dose of 100 mg/kg body weight and MEVA at 200, 300, and 400 mg/kg body weight once daily for 28 days prior to ulcer induction.

Polyphenol-rich extract of Ocimum gratissimum leaves ameliorates colitis via attenuating colonic mucosa injury and regulating pro-inflammatory cytokines production and oxidative stress.

Colitis is a chronic inflammation and ulcer on the inner lining of the large intestine. For many centuries Ocimum gratissimum (OG) leaves have been used in folk medicine in Nigeria to treat inflammatory bowel diseases, however, to date, the anti-colitis effects of OG have not been scientifically proven. In this study we investigated the effects of polyphenol rich extract of Ocimum gratissimum (PREOG) leaf on colonic mucosa injury in colitis, its mechanisms, initial administration time and dosage.

Gastro-protective effect of methanol extract of (del.) leaf on aspirin-induced gastric ulcer in Wistar rats.

This study investigated the protective effects of methanol extract of leaf (MEVA) on aspirin induced gastric ulcer in rats. Thirty Wistar rats, 150-200 g were divided into six groups as follows: Group 1 (control) rats received 2 mL/kg of propylene glycol for 28 consecutive days. Group 2 (Ulcer Control) received 150 mg/kg/day of aspirin suspended in 3 mL of 1% carboxymethylcellulose in water orally for 3 consecutive days during which the rats were fasted for the induction of ulcer.

Protective Effect of Kolaviron on Cyclophosphamide-Induced Cardiac Toxicity in Rats.

Background: Cyclophosphamide (CP) is a nitrogen mustard alkylating drug used for the treatment of chronic and acute malignant lymphomas, myeloma, leukemia, neuroblastoma, adenocarcinoma, retinoblastoma, breast carcinoma, and immunosuppressive therapy. Despite its vast therapeutic uses, it is known to cause severe cardiac toxicity. Kolaviron (KV), a Garcinia kola seed extract containing a mixture of flavonoids, is reputed for its antioxidant and membrane stabilizing properties.

Combined Administration of l-Carnitine and Ascorbic Acid Ameliorates Cisplatin-Induced Nephrotoxicity in Rats.

Objectives: Cisplatin (CIS) is an effective antitumor drug. However, its clinical use is limited due to nephrotoxicity. l-Carnitine and vitamin C are both natural antioxidant that can be obtained from diets.

The Garcinia kola biflavonoid kolaviron attenuates experimental hepatotoxicity induced by diclofenac.

This study sought to investigate the effects of kolaviron on diclofenac-induced hepatotoxicity in rats. Sixty male Wistar rats were divided into 6 groups of 10 rats each as follows: a control group that received oral propylene glycol and treatment groups that received diclofenac alone, diclofenac followed by Livolin Forte (a reference drug), or diclofenac followed by kolaviron at three different doses. At the end of the study period, five rats per group were sacrificed under ketamine hydrochloride anesthetic, 24h after treatment, while the other 5 rats in the group were allowed to recover for 2 weeks before being sacrificed.
