Conducted a study of preparation, diagnosis and study of biological activity of Ligand 4(4-Benzophenol Azopyrogallol) The two-tooth containing the two groups of nitrogen with two similar rings, and the goal of the research is to prepare the ligand above, and after that to prepare the azo-ligand complexes above with the salts of the metal ions selected with a positive charge at fixed rates Sr (II), pb (II), Cd (II), and these compounds were diagnosed with FTIR, UV and XRD, and the fungal activity of ligand and its complexes were diagnosed for staph, E-coli and fungus species. Aspergullus, and some complexes have shown to have antifungal and bacterial efficacy.

Since collagen derived products are highly used in food supplements due to its bioactive properties by influencing cellular and tissue health, flexibility with high effect of repairing and adaptation. It is necessary to carry out safety requirement of an oral chronic toxicity assessment. This study investigated the adverse effect of long term oral administration of collagen-® in pregnant rabbits. We have conducted a thirty days randomized controlled trial in pregnant rabbits. Rabbits were randomized into two groups; Group 1 (control group) were administrated with 1 ml of normal saline PO, SID while Group 2 (collagen-α group) were administered with 1 ml of collagen-α ® PO, SID for one month. Bodyweight gain, viscera weight and histopathological evaluation of the individual rabbit were recorded. The results revealed that the body weight gain and visceral tissues weight in the collagen-α group were significantly lower than the control group. Moreover, various histopathological changes were recorded in heart, lungs, liver and kidneys of the collagen-α group when compared with the non-significant changes that noticed in the control group. Under the conditions of the current study, a high risk of chronic toxic effect was observed in pregnant rabbits inoculated with 1 ml of oral dose of collagen alpha supplement. This result suggests that the adverse effect of collagen derived supplements is overbalancing the benefits.

The current study was carried out to investigate the toxic effects of aflatoxin B1 exposure on heart, lung, and testis of male Albino rats. Twelve healthy male Albino rats were used in the current study. They were divided equally into 2 groups (control and treated groups). The treated group was given aflatoxin B1 orally by a gastric tube at concentration 0.5 mg per kg of body weight for 7 day. The control group was given distilled water alone. At the end of experiment (1 week), the rats were killed under ether anesthesia and the internal organs(heart, lung, and testis) were collected immediately for histological examination. The histopathology examination in heart revealed that there is oedema between myocardial. In lung, there is a large number of inflammatory cells and dilated the alveolar sac with exudates. The testis revealed the excessive vacuolated cells and suppression spermatogenesis. In conclusion, oral dose of aflatoxin B1 exposure could induce a deleterious effect on the histological structure of the heart, lung, and testis of male Albino rats. High level of attention must be taken to prevent the possible contamination of our food with aflatoxin B1.
