Kolaviron: a Bioflavonoid from Seed Extract of Garcinia kola Attenuates Chromium (VI)-Induced Gut Dysfunction and Oxidative Damage in Drosophila melanogaster.

Hexavalent chromium [Cr(VI)] is of public health significance due to its toxicity and carcinogenic effects. Kolaviron, a bio-flavonoid fraction from Garcinia kola seed, has been reported to possess gastroprotective and antioxidative properties. We hypothesize that Kolaviron-fortified diet will attenuate chromium (VI)-induced gut dysfunction and oxidative damage in Drosophila melanogaster.

Cement Dust Exposure Alters Secretory Functions, Biochemical Profile and Morphology of Gastrointestinal Tissues in Rats Exposed to Cement Dust.

Asides direct gastrointestinal exposure, inhalation route is another major xenobiotic exposure pathway to the gastrointestinal tract via mucociliary escalator. This triphasic study assesses cement dust inhalatory exposure effect on the possible alterations of the gastrointestinal tissues and secretion. 72 male, sixteen (16) weeks old Wistar rats were randomized into 3 different phases of 24 animals.

Seeds of Buchholzia coriacea in Diet Mitigate Ischemic Reperfusion-Induced Gastric Ulceration in Experimental Rats.

Buchholzia coriacea (B. coriacea) seeds, in folk medicine, have been documented to prevent gastric ulceration though the mechanism is not fully elucidated. To clarify this, the gastro-healing activities were investigated using graded incorporation of B.

Kolaviron attenuates ischemia/reperfusion injury in the stomach of rats.

Kolaviron (KV), an active complex of at least 3 compounds in Garcinia kola seed, which is known for its antioxidant and anti-inflammatory activity, was investigated for its gastro-protective effect in the stomach of rats subjected to ischemia/reperfusion-induced gastric ulceration. Male adult Wistar rats (180-210 g) were randomized into 6 groups (n = 15) as follows: (i) control, (ii) ulcerated untreated (UU), (iii) KV alone (KVA), (iv) KV + ulcer (KVU), (v) ulcer + KV (UKV), and (vi) ulcer + omeprazole (20 mg/kg). Ulcer was induced through ischemia/reperfusion method after 2 weeks of daily oral KV (100 mg/kg).
