The skin is a complex organ that protects the body from the external environment. The skin has a variety of functions such as providing a physical permeability barrier, protection from infectious agents, thermoregulation, sensation, protection against ultraviolet (UV) rays, regeneration, and wound healing. Clinically, aging skin is characterized by loss of hydration, rough texture, irregular pigmentation, yellowish discoloration, telangiectasia, deep wrinkles or wrinkles, thinning of the skin, and fine lines. One of the plants that can be used as natural ingredients that are rich in antioxidants and interesting to study is avocado (Persea americana Mill.) from the Lauraceae family, which is a plant that has medicinal properties and contains a variety of nutrients. Besides being consumed as food, avocados are also used as a mixture of cosmetic products. This study aims to assess the anti-aging effectiveness of avocado peel extract on increasing collagen levels, elasticity, and hydration in male rats. A total of 25 rats were divided into 5 groups, each group consisting of 5 white rats; control group (ointment base), avocado peel extract ointment group 2.5%, 5%, 7.5%, and 10%. The entire group of rats will be measured the condition before treatment with the Skin Analyzer EH 900 U including levels of collagen, elasticity, and hydration. After measuring the initial skin condition, the treatment was started by applying ointment until it was evenly distributed over the marked area, the ointment was applied according to the groups that have been set above, the application was carried out 2 times a day for 4 weeks. Changes in skin condition were measured weekly for 4 weeks using the EH 900 U skin analyzer. The results of this study indicate that the methanol extract of avocado peel contains phytochemicals in the form of alkaloids, tannins, phenols, flavonoids, and glycosides. Then the phenolic, flavonoid, and tannin content of the avocado peel methanol extract was 59.55 GAE mg/gram extract, 2.96 QE mg/gram extract, and 22.63 TAE mg/gram extract. After 4 weeks of treatment, there was a significant change in the level of hydration, collagen, and skin elasticity (p<0.05) in all treatment groups, this can be seen from the P-value <0.05, with the group of rats receiving the highest concentration of ointment (10%) showed the highest average, namely hydration 49.60%, collagen 40.20%, and elasticity 68.20%. Changes in hydration levels, collagen, and skin elasticity before and after treatment also showed significant changes (P-value < 0.05) with the highest changes found at a concentration of 10%, namely hydration 88.40%, collagen 60.0%, and elasticity 68.20%. In conclusion, the results of this study showed that administration of avocado peel extract ointment could increase hydration, collagen, and skin elasticity levels compared to controls groups, positively correlated with the increase of the duration and the quantity of avocado peel extract ointment were given. The best formulation that gives the most significant effect is 10% avocado peel extract ointment by increasing levels of hydration, collagen, and elasticity the most significantly.

Introduction. Historically, pesticides are evaluated more strictly from a medical point of view than other chemicals. Since their features, such as deliberate introduction into the environment, the possibility of contact with them by large masses of the population, and the high biological activity determine their potential danger to humans. Purpose of research - study of the biological effect of a technical product derived from triazoles when it is repeatedly ingested orally in mammals (rats), establishment of inactive and active doses, justification of the permissible daily dose (DSD) for humans. Material and methods. In acute experiments, white rats were used, including 6 animals in the group. Tested dose: 500-4000 mg/kg of body weight. A chronic (12 months) experiment was performed on 80 male rats with a bodyweight of 180-190 g at the beginning of the study. Tested doses: 5.0; 16.0 and 55.0 mg/kg of body weight (1 control and 3 experimental animals, 20 individuals each). In the dynamics of the experiment, we observed the condition and behavior of animals, water, and food consumption, recorded the timing of death, changes in body weight, physiological, biochemical, and hematological indices. Results. Indices of the acute oral toxicity on the studied product LD50 male rats were 2250 ± 483 mg/kg body weight. The dose of 5.0 mg / kg of body weight was not found to cause significant changes in all studied indices. The doses of 16.0 and 55.0 mg/kg of body weight had a polytropic effect on the body in experimental animals. Discussion. The studied product for the acute oral toxicity refers to low-hazard compounds, the doses of 16.0 and 55.0 mg/kg of body weight has a polytropic effect on the mammalian body, causing changes in carbohydrate, lipid, and lipoprotein metabolism in the body of rats - was accepted as acting. The dose of 5.0 mg / kg of body weight, when administered in rats, there are no changes in all the studied parameters throughout the experiment, is accepted as invalid. Based on the inactive dose-5.0 mg/kg of body weight and taking into account the reserve factor of 100, we have scientifically justified DSD for a person at the level of 0.05 mg/kg. Summary. The conducted sanitary and Toxicological studies indicate the need to assess the toxicity of new technical products to the mammalian body, to increase the reliability of the developed hygiene standards in environmental objects and food products.

Objective: This study was designed to evaluate the effect of the methanol extract of M. foetida (MEMf) on high fat diet-induced obese male rats. Results: HFD induced an increase (P<0.05) in the body and liver weights and the relative abdominal fat pad of the animals in the experimental groups as compared to those in the normal diet group. Also, HFD in the experimental groups reduced (P<0.05) superoxide dismutase and catalase activities, glutathione levels and increased lipid peroxidation in the liver, heart and kidney as well as altered lipid profile (increased serum triglycerides, total cholesterol, low-density lipoproteins (LDL-C), very low-density lipoproteins (VLDL-C), decreased high-density lipoproteins (HDL-C), increased atherogenic index and coronary risk index), when compared to the normal diet animals. All altered parameters were subsequently normalized when obese rats received either MEMf (50 or100 mg/kg) or the reference drug Atorvastatin. Conclusion: This study demonstrates the potential of MEMf to normalize hyperlipidemia, oxidative stress and animal visceral organ weights increased by HFD in rats. Thus, M. foetida is an interesting medicinal plant that could be exploited as sources of anti-obesity agents.

Novice carbon nanostructural material was investigated to estimate its integration to the bone tissue. Wedge osteotomy of a femur bone performed in experimental circumstance on 26 white rats (control=6, experiment=21). Wedge-shaped (h=4 mm, r=3 mm, α=12) implants were crafted from carbon nano-structural material and used to fill bone’s defect. Rats withdrove from the experiment in 3 months. Mechanical properties of the “bone-wedge-bone” block evaluated by the 3-point bending test. Field emission scanning electron microscope used to investigate biocomposite at the bone-to-implant border. The microelements distribution in the samples measured with energy dispersive X-ray analysis. Biomechanical properties of bone-to-implant biocomposite depend on clinical features of consolidation. Anyway, the toughness (T) of bone-to-implant zone is worse than bone-to-bone regenerate significantly (Tcontr = 56.97 MPa, Texp = 47.68 Mpa, Welsh p-value = 2.689e-07). No Ca, or P reveals in the body of implants. The quality and the thickness of the biocomposite on the bone-to-implant border predetermine clinical results of bone substitution. The absence of microelements inside the body of implants confirms that the implant structure is too subtle. Increasing porosity of material and creation of transverse channels can improve bone conduction and scaffold quality of carbon nano-implants.

Introduction: Beetroot (Beta vulgaris L.) contains flavonoid compounds that play a role in the haematopoietic process. It is known that methanol extract of beetroot has benefits in the process of haematopoiesis in normal white rats. Aims: To evaluate the beetroots extracts as hematopoietic agents on male rats. Methods: Beetroots dried powder was divided into two parts. One part was macerated separately with dichloromethane and 70% ethanol, while the other part is added with citric acid and washed with water to remove alkaloids and then extracted with 70% ethanol. The study used 24 rats which were divided into four groups. Each group consisted of 6 rats, namely the normal group, dichloromethane extract group, ethanolic extract group, and free alkaloids-ethanolic extract group. Each extract was given at a dose of 200 mg.Kg-1 for 21 days. Analyzed blood parameters are erythrocytes, haemoglobin, MCV, MCH, MCHC, leukocytes, and platelets. The data obtained consisted of the number of cells analyzed using one-way ANOVA then obtained by the Tukey test. Results: This study showed a significant increase in the number of erythrocytes, haemoglobin, MCV, MCH, MCHC, leukocytes, and platelets in rats that were given each extract compared to the normal group (p <0.05). The ethanolic extract of beetroot can increase erythrocytes, haemoglobin, MCV, MCH, MCHC, leukocytes, and platelets by 41.49%, 24.95%, 14.92%, 33.54%, 27.19%, 59.40%, and 35.37%, respectively. Conclusions: The ethanolic extract of beetroot has the potential as a good natural haematopoietic agent.

Introduction. Due to their high biocompatibility, substances based on nanosized selenium particles, encapsulated in natural or synthetic polymer matrices, are promising materials for the creation of biomedical preparations of diagnostic and therapeutic value. Selenium nanoparticles are successfully used in the diagnosis of various types of cancer. In addition to the diagnostic value, selenium nanoparticles have their own prophylactic and oncological effect. This paper presents the results of a study of the toxicity of the Se nanocomposite encapsulated in the polymer matrix of arabinogalactan (SeAG). The emergence and development of the pathological process in the tissue of the brain, liver and kidneys during subacute administration of this nanocomposite was studied.Materials and methods. Twenty white outbred male rats weighing 200–220 g were used in the work. Animals were orally administered a solution of the selenium nanocomposite at a dose of 500 μg per kilogram of animal body weight for 10 days. Then, using the methods of histological analysis, the severity of the biological response of the organism to the introduction of this nanocomposite was assessed. An analysis of the state of the tissue of the liver, kidneys and the sensorimotor cortex of the brain was carried out.Results. With the intragastric administration of this drug, there is stasis of blood in the portal tracts, a pronounced macrophage reaction and diapedesis of leukocytes in the liver tissue. There is a decrease in the number of normal neurons per unit area, a decrease in the number of astroglia cells and an increase in the number of  degeneratively altered neurons in the tissue of the sensorimotor cortex. There is also an increase in connective tissue in the cortex of the kidney, with the formation of fibrosis and a decrease in the area of the Shumlyansky – Bowman capsule.Conclusion. The effect of the investigated nanocomposite is characterized by the development of a pronounced pathological process in the central nervous and hepatorenal systems of the body.

BACKGROUND: Excessive and heavy physical activity could lead to the oxidative stress in the body. This condition can affect several blood parameters such as malondialdehyde (MDA), glutathione peroxidase (GPx), leukocytes, and its type counts. One way to overcome the effects of oxidative stress due to strenuous physical activity is by giving natural antioxidants. Mangosteen rind (Garcinia mangostana L.) contains considerable antioxidants, namely, xanthones and procyanidin. AIM: This research aimed to investigate the effect of mangosteen rind extract (MRE) on oxidative stress parameters, leukocyte count, and leukocyte count in male rats (Rattus norvegicus) that received excessive physical activity. METHODS: This study was purely experimental research with a post-test only control group design, using 29 white rats (R. norvegicus) as experimental animals, which were divided into four groups. The first group (P1) received distilled water and the other group received MRE at a dose of 50 mg/KgBW (Body Weight) (P2), 100 mg/KgBW (P3), and 200 mg/KgBW (P4) for 3 weeks, respectively. Swimming as a physical activity was carried out 3 times a week in all groups. Examination of leukocyte count and species was carried out on the last day of treatment after the rats swam to fatigue. RESULTS: MDA levels did not decrease significantly while GPx activity increased significantly. Moreover, the average leukocytes and lymphocytes showed a decrease but not significant. A significant decrease in the percentage of neutrophils and basophils was obtained by P4 group compared to others. In addition, a significant decrease in the average percentage of eosinophils for P3 and P4 groups was obtained. Furthermore, P3 and P4 group exhibit significant increase of the average percentage of monocytes. CONCLUSION: MRE as an antioxidant affects the levels of neutrophils, basophils, eosinophils, and monocytes but not in MDA, GPx, leukocytes, and lymphocytes.

Glucose is an important carbohydrate which is more absorbed into the bloodstream as glucose and other sugar is changed into glucose in the liver. Blood glucose level is closely related to diabetes mellitus. Diabetes mellitus is a disease that arises in a person which is indicated by the presence of blood glucose levels exceeding normal (hyperglycemia) due to the deficiency of the insulin hormone in the body. The design of this research was using RAL with 24 male rats that divided into 6 treatments which were normal with the giving of Na-CMC 0.5% 1mL/200 gram BB, negative with the giving of Na-CMC 0.5% 1mL/200 gram BB, positive with the giving of glibenclamide of 0.45 mg/kg BB and 3 other treatments by giving catfish biscuit (Formula A, Formula B, and formula C) with 4 replications. All treatments were injected with monohydrate alloxan at a dose of 150 mg/kg BW, except for the normal treatment. The results showed that the formulation of catfish biscuit can lower the blood glucose level of white rats. The composition of biscuit with formula C has the highest decreasing percentage which was 80.20% to the blood glucose level of white rats.
