[Effects of saffron (Crocus sativus l. iridaceae) on blood level of follicle-stimulating hormone, and number and dynamics of body weight of offspring in female rats].

This paper reviews the effects of saffron Сrocus sativus L. Iridaceae which grow in Azerbaijan on blood level of follicle-stimulating hormone (FSH), and number and dynamics of body weight of offspring in female rats. The findings indicated that the per os administration of alcoholic extract of saffron was able to decrease the FSH levels in blood of the 12-month-old rats as compared to that in the control group, involving the animals of the same age which have not received the saffron extract, and was close to the FSH levels reported for the 6-month rats. There was also an increase in number and body weight of pups from rats receiving the saffron extract prior to pairing with the intact males.

[The effect of Hirudo therapy on a change in the activity of retinal transport adenosinetriphosphatases in the rabbit with photic eye damage]. / Vliianie girudoterapii na izmenenie aktivnosti transportnykh adenozintrifosfataz setchatki krolika pri svetovom povrezhdenii glaz.

Effect of Hirudo therapy on the activities of transport adenosine triphosphatases (ATPases) of the retina and pigmented epithelium (PE) is studied in normal and albino rabbits whose eyes were exposed to potent illumination (100,000 Lux at the level of the cornea for 90 min). The exposure decreased the activities of ATPase, which did not recover in any of animal groups. Hirudo therapy immediately after illumination increased the enzymes activity in pigmented animals in comparison with intact control: by 20% in the retina and by 23% in PE; Mg-ATPase activity increased by 23% in the retina and decreased by 10% in PE. In subsequent 24 h, ATPase activities decreased, but in comparison with exposed retina the activity of Na,K-ATPase in the retina was 70% increased and in PE 78% increased; the activities of Mg-ATPase were increased by 33 and 8%, respectively. Complete recovery of ATPase activities was attained in 8 days. In albino animals, ATPase activities did not recover completely, but they were notably higher than in intact controls. Hirudo therapy before illumination had a marked protective effect.

[Effects of Hirudo therapy on lipid peroxidation and catalase activity of the rabbit retina after light-induced eye injuries]. / Vliianie girudoterapii na perekisnoe okislenie lipidov i aktivnost' katalazy setchatki krolika pri svetovom povrezhdenii glaz.

Effect of Hirudo therapy on the level of lipid peroxidation (LPO) products and catalase activity in the retina and pigmented epithelium (PE) after exposure to intensive illumination is assessed. Light injury to the eye (100,000 lux in 90 min) leads to accumulation of LPO products and suppression of catalase activity. Hirudo therapy after potent light exposure of the eye decreased the level of hydroperoxide and malonic dialdehyde and normalized retinal and PE catalase activity, thus exerting a therapeutic antioxidant effect. Hirudo therapy before illumination did not notably protect the eye as regards the content of LPO products and catalase activity.

[Comparative assessment of antioxidant activity of para-aminobenzoic acid and emoxipin in retina]. / Sravnitel'naia otsenka antioksidantnoi aktivnosti paraaminobenzoinoi kisloty i émoksipina v setchatke.

Effect of para-aminobenzoic acid (PABA) on lipid peroxidation (LPO) in rat and guinea pig retina exposed to hypoxic hypoxia is studied. PABA was injected intraperitoneally and parabulbarly before and after hypoxic exposure. Antioxidant activities of PABA and emoxipin were compared. An intraperitoneal injection of PABA in a dose of 10 mg/kg 24 h before hypoxia virtually completely prevented accumulation of lipid peroxides and preserved catalase activity in the retina. Parabulbar injection of 0.01% PABA solution 1 h before hypoxia prevented LPO intensification, stabilized catalase activity in hypoxia, and protected the retina starting from the moment immediately after hypoxic exposure. The efficacy of 0.01% PABA is comparable with that of 1% emoxipin, and a 0.01% solution of emoxipin is less effective than PABA in the same concentration. PABA exerts an antioxidant effect after hypoxia by decreasing the abnormally high level of lipid peroxides and reducing catalase activity in the retina after parabulbar injection of the drug. All the studied concentrations of the drug (from 0.007 to 0.08%) are active, but the optimal dose for the retina is 0.04%. By its efficacy this concentration is equivalent to 1% emoxipin.

[The effect of L-DOPA on the accumulation of lipid peroxidation products in separate brain structures during irradiation]. / Vliianie L-DOFA na nakoplenie produktov perekisnogo okisleniia lipidov v otdel'nykh strukturakh mozga pri obluchenii.

A study was made of the effect of L-DOPA on the dynamics of changes in lipid peroxidation products (LPP) and the content of various types of SH groups in certain brain structures (oblongata, cerebellum, visual and sensorimotor cortex) and their synaptosomal fractions upon irradiation. The preadministration of L-DOPA to irradiated rats inhibited LPP accumulation, prevented the decrease in the content of various types of thiols and thus exerted an antioxidant effect.

[Lipid peroxidation and ATPase activity in synaptosomal and mitochondrial fractions of the brain in hypoxia]. / Perekisnoe okislenie lipidov i aktivnost' ATFaz v sinaptosomal'nykh i mitokhondrial'nykh fraktsiiakh mozga pri gipoksii.

Acute hypoxia was accompanied by intensification of lipid peroxidation in synaptosomal and mitochondrial rat brain fractions as well as by inhibition of Na+, K+- and Mg2+-ATPases. Preadministration of antioxidants vitamin E and ionol into animals prevented distinctly the increase in lipid peroxidation rate, while the ATPases activity was unaltered. Inhibition of the ATPases may be considered as a result of impairing effect of the lipid peroxidation products, which appears to be of importance for structure-functional deteriorations of the nervous system in hypoxia.

[Lipid peroxidation in the synaptosomal and mitochondrial fractions of separate brain structures in hypoxia]. / Perekisnoe okislenie lipidov v sinaptosomal'noi i mitokhondrial'noi fraktsiiakh otdel'nykh struktur mozga pri gipoksii.

The paper studies intensification of lipid peroxide oxidation in separate brain structures (the medulla oblongata, cerebellum, visual and sensomotor cortex), synaptosomal and mitochondrial fractions under hypoxia. It has been established that acute hypoxia increases accumulation of lipid peroxidation (LPO) products, hydroperoxide and malonyl dialdehyde. Intensification of LPO in synaptosomes and mitochondria is more pronounced as compared to the whole structures. Preliminary treatment with antioxidants (vitamin E and ionol) considerably suppressed LPO intensity under both hypoxia and hypoxia with reoxygenation. Intensification of LPO in synaptosomes and mitochondria is suggested to be the key point in structural-functional disturbances of the nervous system under hypoxia and ischemia.
