Abstract

Water stress can limit the growth and production of cowpea (Vigna unguiculata (L.) Walp.), necessitating the use of strategies that induce plant tolerance to mitigate its effects on the crop. This includes the application of salicylic acid (SA) and antitranspirant polymer (AP). The objective of this study was to evaluate the effect of SA and AP applications on the growth and production of cowpeas subjected to water stress. The experiment was conducted in field conditions at Sítio Boqueirão, Catolé do Rocha, Paraíba, Brazil. The experimental design used was randomized blocks, comprising 10 treatments with four replications. The evaluated treatments included nine combinations generated according to the Central Composite Design experimental matrix, involving five doses of SA and five doses of AP applied to plants under water stress, along with an additional treatment (without water stress and application of SA and AP). The assessed variables included morphological parameters and yield. The data were subjected to canonical correspondence analysis and confidence ellipses. The application of SA and AP increased growth (summer and spring) and productivity (summer). However, in spring, there was a decrease in productivity and an increase in the number of days until the initiation of pod harvesting in cowpeas under water stress.

Abstract

Purpose: estimation of the possibility of using a mixture of feed additive "BioGrom SC" and the food antibiotic "Monenzin" for normalizing metabolic processes in highly productive cows in the transit period.Materials and methods. Studies were conducted because of the tribal plant of the Leningrad region. Two groups of animals were selected on the principle of analogs (experimental and control) 20 goals in each. The experimental group of cows 21 days before the calving and for 14 days after the calves were given a mixture of feed additive "BioGrom SC" and the food antibiotic "Monenzin". For the cottage additives, calcium carbonate (chalk) was used as a filler in the amount of 250 g with the addition of 10-15 g. Supplements "BioGrom SC" by 1 head. The mixture was prepared at the rate of 20 goals and a food antibiotic "Monenzin" was added to it at the rate of 100 mg per 1 kg of a mixture of feed additive with filler. The resulting mixture was fed by animals of the experimental group. All animal experimental and control groups take blood for 21 days before the hotel. The total protein, beta hydroxy acid, acetoacetic acid, alkaline blood reserve, calcium-phosphoric ratio, glucose is determined. At the end of the transit period on the 21st day of lactation, the blood of animal control and experimental groups was repeatedly investigated.Results. In the cows of the experimental group, in comparison with the cows of the control group at the end of the transit period, a decrease in such biochemical indicators was observed as beta hydroxy acid (a decrease to 0.84 ± 0.03 mmol / l), acetoacetic acid (decrease to 0.4 ± 0, 04 mmol / l). The animals of the experimental group decreased the content of the general protein (77.0 ± 0.08 g / l). Also, the data of the backup alkalinity of blood (acidose indicator) are within reference values. Calcium phosphorus ratio was also within the normal range.Conclusion. Introduction to the diet of a mixture of feed additive "BioGrom SC" and food antibiotic "Monenzin" normalize some biochemical blood indicators in cows in the transit period. At the same time, without correction of metabolic processes, cows are observed ketosis and acidosis, which can lead to premature disposal of animals from herd and as a result of economic losses. Thus, the use of the mixture is shown for the prevention and treatment of acidosis of the scar, metabolic acidosis, ketosis in cattle of the dairy direction of productivity.

4. A Case of Ichthyosis Vulgaris and the Use of 70% Glycolic Acid Chemical Peels for Management.

Abstract

Ichthyosis vulgaris is the most common of the inherited ichthyoses, with a semi-autosomal dominance. Approximately 37-50% of people affected have associated atopic eczema and a similar proportion have atopic relatives. In this case report, we present a 15-year-old female with a history of atopic eczema who clinically presented with asymptomatic, brown, scaly patches on the extensor surfaces of the lower limbs and flexural surfaces of the upper limbs, sparing the flexural creases on all limbs. She also had neck, abdominal, and mild truncal involvement. A clinical diagnosis of ichthyosis vulgaris was made and the differential diagnoses of X-linked recessive ichthyosis, pityriasis rubra pilaris, and xerotic dermatitis were entertained. While waiting for the histological report, she was maintained on 5% glycerine in aqueous cream for daily moisturizing with alternating nightly applications of 10% glycolic acid lotion and a 5% salicylic acid mixture. The diagnosis of ichthyosis vulgaris was confirmed by histopathological findings of hyperkeratosis and an absent granular layer. She then received a 70% glycolic acid in-office chemical peel on the abdomen to test for the cosmetic outcome. The glycolic acid peel was approximately 90% efficacious in reducing the hyperkeratinization and is recommended as an adjunctive biannual maintenance regime in combination with other topical therapies such as daily emollients, topical alpha/beta hydroxy, and/or urea compounds., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Palmer et al.)
