Protective and antigenotoxic effect of Ulva rigida C. Agardh in experimental hypothyroid.

The presence of chromosomal damage in bone marrow cells affected by several diseases such as thyroid, cancer etc., was detected by the micronucleus (MN) assay. The present study was designed to evaluate: i) volatile components of Ulva rigida, ii) effects of hypothyroidism on bone marrow MN frequency, iii) effects of oral administration of Ulva rigida ethanolic extract (URE) on MN frequency produced by hypothyroidism, and iv) thyroid hormone levels in normal and 6-n-Propylthiouracil (PTU)-induced hypothyroid rats.

Ulva rigida improves carbohydrate metabolism, hyperlipidemia and oxidative stress in streptozotocin-induced diabetic rats.

This study was designed to investigate the effects of Ulva rigida, one of the green algae, on the lipid profile and oxidative-antioxidative systems in streptozotocin-induced diabetic rats. Forty Wistar rats randomly divided into four groups: control (C), control + U. rigida extract (C + URE), diabetes (D) and diabetes + U.

Anti-hyperglycemic and antigenotoxic potential of Ulva rigida ethanolic extract in the experimental diabetes mellitus.

An increased reactive oxygen species (ROS) and insufficient antioxidant activity is known in diabetes mellitus (DM). Antioxidant compounds in the human foods or supplementary diets can be used to counteract several diseases. The analysis of micronuclei (MN) is a cytogenetic technique used to show chromosomal damage caused by clastogenic affects.

Vanadyl sulfate, taurine, and combined vanadyl sulfate and taurine treatments in diabetic rats: effects on the oxidative and antioxidative systems.

Background: Vanadyl sulfate (VS) and taurine are two promising agents in the treatment of diabetes related to their antihyperglycemic, antihyperlipidemic, and hyperinsulinemic effects. Data about the effects of VS on the oxidant-antioxidant system is limited and controversial. However, taurine is a well-documented antioxidant agent and our aim was to investigate the effects of VS, taurine and VS and taurine combination on the oxidative-antioxidative systems in streptozotocin-nicotinamide (STZ-NA) diabetic rats.
