Abstract: To understand the treatment of malaria, it is important to understand the effect of the administration of specific anti-malarials on various physiological variables. Current study investigated the effect (s) of the anti-malarial, coartem and co-administration of the antioxidant, Vitamin E on the levels of Luteinising and Follicle Stimulating Hormones [LH and FSH] of malaria parasite infected mice. Twenty-eight (28) adult mice were obtained, acclimatized for two (2) weeks and randomly selected into four (4) groups of seven (7) rats per group. Group 1 (Control) received standard mice diet and water ad libitum, while group 2 mice were infected with malaria (Plasmodium berghei) and left untreated. Groups 3 and 4 were inoculated with malaria (Plasmodium berghei); then treated with coartem and coartem + vitamin E respectively. After three (3) weeks of administration of test substance, the mice blood samples were obtained from mice (for each group) and assayed for serum FSH and LH levels. Statistical comparison was then conducted (using the student t-test) against those of control group to ascertain the effects of the changes due to coartem and/or antioxidant vitamin E co-administration to plasmodium berghei infected mice. Study found a statistically significant increase in serum LH levels of male mice after inoculation with plasmodium berghei. This decrease was noticed more even with coartem and antioxidant vitamin E co-administration, implicative of a possible effect in fecundity levels of infected male mice. The level of FSH was significantly increased in infected mice, but however showed a reversal following treatment with coartem and/or antioxidant vitamin E. The effects on reproductive hormones seen here may mirror the effects in man. More studies are needed to elucidate that.

Abstract: The effect of blue and red light on the activity of catalase and ascorbate peroxidase, the content of proteins and soluble carbohydrates in the leaves of wheat varieties under the action of sodium chloride was investigated. The objects of the research were bread wheat Saratovskaya-29 (Triticum aestivum L.) and durum wheat Barakatli-95 (Triticum durum Desf.). Plants were grown in laboratory conditions in an aqueous medium using a Knoop nutrient medium. Experimental plants were coated with transparent films transmitting light at wavelengths of 420-480 nm (blue light) and 640-680 nm (red light). During the growing season, samples of fully formed leaves were taken for physiological and biochemical studies every week at 11 a. m. Under the action of sodium chloride, the accumulation of hydrogen peroxide in white light was higher than in blue and red light. Low catalase activity also observed in blue and red light under the action of sodium chloride in both varieties. In the bread wheat variety Saratovskaya -29 the level of hydrogen peroxide, the activity of catalase and ascorbate peroxidase enzymes were lower than those of the Barakatli-95 durum wheat variety. Blue light stimulated the synthesis of proteins, while red light stimulated the synthesis of carbohydrates. Blue and red light prevented the formation of H2O2 under the action of NaCl.

Abstract: The effect of white, blue and red light on the relative humidity of the leaves, as well as on the content of photosynthetic pigments, the activity of photosystem-2, the content of proteins and soluble carbohydrates in the leaves of tomato varieties were studied. Photosynthetic pigments were determined by the method of leaf homogenization, in 96% ethanol, with further centrifugation at 200 g. Measurements were conducted using a spectrophotometer at wavelengths of 665, 649 and 440.5 nm. The content of soluble sugars was determined at wavelengths of 630-570 nm by the accelerated bichromate method. The protein content was determined on a spectrophotometer SP 2000, at wavelengths of 230 and 260 nm. Studies have shown that during the influence of red light, there is a slight decrease in the protein content, an increase in the content of photosynthetic pigments and soluble carbohydrates in all varieties of tomatoes grown in red light. Unlike red light, blue light stimulated the synthesis of proteins in leaves. Red light promotes the synthesis and accumulation of carbohydrates, while blue light encourages the synthesis of proteins in tomato leaves.
