Impediment of selenite-induced cataract in rats by combinatorial drug laden liposomal preparation

The article gives the results of the research on the influence of a developed complex liposomal preparation on the dynamics of morphological and biochemical indicators of the blood of rats subjected to modeled oxidative stress caused by intermuscular injection of 50% carbon tetrachloride at a dose of 0.25 ml per 100 g of body mass. We found that in conditions of intoxication by carbon tetrachloride, the physiological level of hematological indicators of the researched animals’ body was disrupted. This is indicated by the reduction in the amount of erythrocytes, hemoglobin content, concentration of hemoglobin per erythrocyte, increase in the amount of leucocytes, mass of hemoglobin per erythrocyte and increase of colour indicator. Also, we detected suppression of protein synthesis function of the liver. The levels of total protein and albumin fraction were below the normal physiological level. High indicators were observed in the levels of creatinine, urea and total bilirubin. In order to normalize the functional state of the liver under oxidative stress it is reasonable to use a liposomal preparation which contains butafosfan, interferon, thistle and vitamins. In order to normalize morphological and biochemical indicators of the blood of rats subject to intoxication of carbon tetrachloride it is reasonable to use a liposomal preparation that contains butafosfan, selenium, thistle, methionine and vitamins. Using the liposomal preparation Butaselmevit for rats under oxidative stress the morphological and biochemical indicators in the blood normalized. On the 14th day the indictors of the number of erythrocytes, the hemoglobin content, the white blood cell count and red blood indexes compared to control came within the physiological indicators, indicating a recovery of hematopoietic function of the bone marrow and normalized indicators of the functional state of the liver.

The results of research on the influence of the elaborated complex immunotropic drug containing butafosfan, interferon, thistle and fat-soluble vitamins A, D3, E in the form of a liposomal emulsion on the activity of T- and B-cell chains of immunity in rats under the conditions of action on the body of oxidative stress are presented. It has been established that the introduction of 50% tetrachloromethane into the rats of the first and second experimental groups, with a dose of 0.25 ml per 100 g of body weight, causes oxidative stress in them which negatively affects the cellular immunity and functional activity of immunocompetent blood cells. Immunosuppressive effects of oxidative stress were manifested by a decrease in the blood of rats in the first and second experimental groups of the number of T- and B-lymphocytes and their regulatory subpopulations mainly on the 2nd and 5th day of the study. At the same time, in the blood of rats of the first experimental group in all research periods a decrease in the relative number of common, active and theophylline-resistant T-lymphocytes, as well as B-lymphocytes was observed with a noticeable increase in the number of their undifferentiated forms. At the same time, the obtained data suggest the positive effect of butafosfan, interferon, thistle and vitamins A, D3, E in the liposomal preparation on the relative amount of T- and B-lymphocytes and on the redistribution of avidity in the direction of strengthening the receptor field of plasma membranes immunocompetent cells. It was found that the normalization on the 2nd day of blood level in the second experimental group of common T-lymphocytes occurred due to the secondary forms of the blood and active T-lymphocytes by changes in the number of low-avid forms. In addition to the indicators characterizing the cellular immunity of rats, the components of the liposomal preparation showed regulatory influence on the humoral link of the immune response. In particular, on the 10th day of research in blood of rats of the second experimental group a tendency towards an increase in the relative number of B-lymphocytes and an increase in the number of cells with low and medium density of receptors was found, which, under the conditions of oxidative stress, indicates an increase in the body's ability to actively synthesize protective antibodies

The effects of a liposomal preparation of lipophilic immunomodulator β-D-GlcNstearoyl-(1-4)-norMurNAc-L-Abu-D-isoGln (N-L18-norAbu-GMDP) were investigated on resistance toCryptosporidium parvuminfection in neonatal kids. The liposomal preparation was administered subcutaneously or intranasally/orally (i.n./p.o.) twice at doses of 100 μg, 200 μg, or 1000 μg per kid pre-infection challenge. The treatment schemes were (i) 72 and 24 h pre-infection challenge, (ii) 24 h pre-infection challenge and 24 h post-infection challenge (oral inoculation with 1×107oocysts ofC. parvumin 5 ml of PBS). Administration of liposomal N-L18-norAbu-GMDP by i.n./p.o. route at the cumulative dose of 2000 μg per kid 72 and 24 h pre-infection challenge, lead to substantially increased clearance of coccidian parasites from various parts of the intestine. On the basis of histological examination, the distribution of cryptosporidia in the intestine and the severity of the infection, treated kids were classified on day 5 as having a strong reduction in infection in comparison to the control group (P<0·05). No cryptosporidia were found on the mucosal surface of treated kids by day 10, while the intestines of the control kids were still infected. All doses and routes of administration were judged effective with respect to suppression of cryptosporidia infections.
