Working in high temperature environment is unavoidable condition for an outdoor worker, especially the outdoor workers in to tropical countries such as Indonesia. Heat stress leads to various heat-related illnesses, such as heat stroke, hyperthermia, heat exhaustion, heat cramps or heat rashes.  A mild and moderate heat stress usually less serious and did not harm general health condition, however it could cause individual fatigue and unfocused, which will interfere the working performance and productivity. Heat stress will had caused physiologic response of the body, as it needs to reduce the increased temperature inside the body; known as heat strain condition.

Effects of haematinics on body weight gain and certain haematological values were studied on nine sheep of 1 to 2 years old, divided into three groups (A, B & C), each consisting of 3 sheep during the period from 15 January to 28 February 2002. Sheep of group B were treated with copper sulphate and cobalt sulphate @ 50 mg and 1 mg / head / day respectively and the sheep of group C, in addition to copper and cobalt sulphate, were treated orally with ferrous sulphate @ 200 mg / head / day along with IM injection of Vit-B12 (B50 Forte®, Square) @ 5 ml / sheep every 15 days interval for a period of 45 days whereas group A served as untreated control. Results showed that the body weight gain were significantly (p < 0.05) increased in the haematinics treated groups B and C (12.67 ± 2.33 g and 13.57 ± 2.24 g respectively) in comparison to control (9.37 ± 0.58 g) at 45 days of treatment. Haematological examination showed significantly (p < 0.01) increased haemoglobin (9.33 ± 0.42 g% and 10.0 ± 0.06 g%), packed cell volume (29.0 ± 0.58 % and 30.0 ± 0.58 %), total erythrocyte count (9.67 ± 0.22 and 10.27 ± 0.25 106 / mm3), and mean corpuscular haemoglobin concentration (32.26 ± 0.83 and 32.28 ± 0.53%) in the treated groups B and C at 45 days of treatment respectively. The present findings indicate that the supplementation of haematinics could be used in improving the general health condition in sheep and the haematological values.Key words: Haematinics; body weight; haematological values; Black Bengal goatsdoi: 10.3329/bjvm.v2i2.2559Bangl.

Mushrooms like Ganoderma lucidum have been used for thousands of years as a traditional medicine in the Far East. Ganoderma received wide popularity as an eating mushroom with high nutritive value, but even more as medical fungi. It has been used for the treatment of various diseases: hepatitis, hypertension, insomnia, and even cancer. Due to its extraordinary action, it is often called 'Elixir of life', 'Food of gods' and 'Mushroom of universe'. The intracellular and extracellular polysaccharides (b-glucane) inhibit the growth of several types of cancer. Mushroom produces triterpenes of which especially ganoderic acid showed cytotoxicity on primary tumor liver cells, inhibition of histamine release, hepatoprotective effect, stimulation of the immune system functions, inhibition of the aggregation of blood plates, etc. On the other hand, beer as a purely natural beverage obtained in the process of fermentation, contains a number of ingredients which are important for human organism, and in moderate usage has favorable reaction on the general health condition of the body. As such, beer is a very good basis for the development of a number of new products with defined pharmacodynamics influence. In this work, we have investigated the possibilities of using extracts of mushroom Ganoderma lucidum in the production of special beer types. The composition of mushroom, properties of the most important active ingredients, extraction procedures, and sensory characteristics of the beers on the basis of such extracts were determined. The most important parameters of quality and possibility of adjustments using extracts of different medicinal herbs were investigated.

Heat-induced ifiness is preventable. Physicians, teachers, coaches, and parents must be made aware of the potential hazards of high-intensity exercise in hot climates and of the measures needed to prevent heat-related illness in preadolescents. Because of the following morphologic and functional differences, exercising children do not adapt to extremes of temperature as effectively as adults when exposed to a high-climatic heat stress.1 1. Children have a greater surface area-mass ratio than adults, which induces a greater heat transfer between the environment and the body. 2. Children produce more metabolic heat per mass unit than adults when walking or running.2 3. Sweating capacity is not as great in children as in adults.3,4 4. The capacity to convey heat by blood from the body core to the skin is reduced in the exercising child.4,5 The foregoing characteristics do not interfere with the ability of the exercising child to dissipate heat effectively in a neutral or mildly warm climate. However, when air temperature exceeds skin temperature, children have less tolerance to exercise than do adults. The greater the temperature gradient between the air and the skin, the greater the effect on the child.4,6,7 Upon transition to a warmer climate, any exercising individual must allow time for conditioning for heat (acclimatization). Intense and prolonged exercise undertaken before acclimatization may be detrimental to health and might even lead to fatal heat stroke.8 Although children can acclimatize to exercise in the heat,6,9 the rate of their acclimatization is slower than that of adults.1 Therefore, a child will need more exposures to the new climate to sufficiently acclimatize.

Background: Biocompatible polymers are gaining great interest in the field of biomedical applications. The term biocompatibility refers to the suitability of a polymer to body and body fluids exposure. Biocompatible polymers are both synthetic (man-made) and natural and aid in the close vicinity of a living system or work in intimacy with living cells. These are used to gauge, treat, boost, or substitute any tissue, organ or function of the body. A biocompatible polymer improves body functions without altering its normal functioning and triggering allergies or other side effects. It encompasses advances in tissue culture, tissue scaffolds, implantation, artificial grafts, wound fabrication, controlled drug delivery, bone filler material, etc. Objectives: This review provides an insight into the remarkable contribution made by some well-known biopolymers such as polylactic-co-glycolic acid, poly(ε-caprolactone) (PCL), polyLactic Acid, poly(3- hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), Chitosan and Cellulose in the therapeutic measure for many biomedical applications. Methods: : Various techniques and methods have made biopolymers more significant in the biomedical fields such as augmentation (replaced petroleum based polymers), film processing, injection modeling, blow molding techniques, controlled / implantable drug delivery devices, biological grafting, nano technology, tissue engineering etc. Results: The fore mentioned techniques and other advanced techniques have resulted in improved biocompatibility, nontoxicity, renewability, mild processing conditions, health condition, reduced immunological reactions and minimized side effects that would occur if synthetic polymers are used in a host cell. Conclusion: Biopolymers have brought effective and attainable targets in pharmaceutics and therapeutics. There are huge numbers of biopolymers reported in the literature that has been used effectively and extensively.

AbstractSituational or persistent body fluid deficit (i.e., de- or hypo-hydration) is considered a significant health risk factor. Bioimpedance analysis (BIA) has been suggested as an alternative to less reliable subjective and biochemical indicators of hydration status. The present study aimed to compare various BIA models in the prediction of direct measures of body compartments associated with hydration/osmolality. Fish (n = 20) was selected as a biological model for physicochemically measuring proximate body compartments associated with hydration such as water, dissolved proteins, and non-osseous minerals as the references or criterion points. Whole-body and segmental/local impedance measures were used to investigate a pool of BIA models, which were compared by Akaike Information Criterion in their ability to accurately predict the body components. Statistical models showed that ‘volumetric-based’ BIA measures obtained in parallel, such as distance2/Rp, could be the best approach in predicting percent of body moisture, proteins, and minerals in the whole-body schema. However, serially-obtained BIA measures, such as the ratio of the reactance to resistance and the resistance adjusted for distance between electrodes, were the best fitting in predicting the compartments in the segmental schema. Validity of these results should be confirmed on humans before implementation in practice.

Poultry are one of the most vulnerable species of its kind once the temperature-humidity nexus is explored. This is so because the broilers lack sweat glands as compared to humans and undergo panting process to mitigate their latent heat (moisture produced in the body) in the air. As a result, moisture production inside poultry house needs to be maintained to avoid any serious health and welfare complications. Several strategies such as compressor-based air-conditioning systems have been implemented worldwide to attenuate the heat stress in poultry, but these are not economical. Therefore, this study focuses on the development of low-cost and environmentally friendly improved evaporative cooling systems (DEC, IEC, MEC) from the viewpoint of heat stress in poultry houses. Thermodynamic analysis of these systems was carried out for the climatic conditions of Multan, Pakistan. The results appreciably controlled the environmental conditions which showed that for the months of April, May, and June, the decrease in temperature by direct evaporative cooling (DEC), indirect evaporative cooling (IEC), and Maisotsenko-Cycle evaporative cooling (MEC) systems is 7–10 °C, 5–6.5 °C, and 9.5–12 °C, respectively. In case of July, August, and September, the decrease in temperature by DEC, IEC, and MEC systems is 5.5–7 °C, 3.5–4.5 °C, and 7–7.5 °C, respectively. In addition, drop in temperature-humidity index (THI) values by DEC, IEC, and MEC is 3.5–9 °C, 3–7 °C, and 5.5–10 °C, respectively for all months. Optimum temperature and relative humidity conditions are determined for poultry birds and thereby, systems’ performance is thermodynamically evaluated for poultry farms from the viewpoint of THI, temperature-humidity-velocity index (THVI), and thermal exposure time (ET). From the analysis, it is concluded that MEC system performed relatively better than others due to its ability of dew-point cooling and achieved THI threshold limit with reasonable temperature and humidity indexes.

The central body temperature of a man rises gradually during the first half hour of a period of work to a higher level and this level is precisely maintained until the work is stopped; body temperature then slowly declines to the usual resting level. During prolonged work the temperature regulatory center in the hypothalamus appears to be reset at a level which is proportional to the intensity of the work and this setting is independent of environmental temperature changes ranging from cold to moderately warm. In hot environments the resistance to heat loss may be so great that all of the increased metabolic heat of work cannot be dissipated and the man's central temperature will rise above the thermostatic setting. If this condition of imbalance is continued long enough heat stroke will ensue. We have found that in a 3 mile race lasting only 14 minutes on a hot summer day a runner's rectal temperature may rise to 41.1°C., with heat stroke imminent. The physiological regulation of body temperature of men in warm environments and during the increased metabolic heat production of work is dependent on sweating to provide evaporative cooling of the skin, and on adjustments of cutaneous blood flow which determine the conductance of heat from the deeper tissues to the skin. The mechanisms of regulating these responses during work are complex and not entirely understood. Recent experiments carried out in this laboratory indicate that during work, sweating may be regulated by reflexes originating from thermal receptors in the veins draining warm blood from the muscles, summated with reflexes from the cutaneous thermal receptors, both acting through the hypothalamic center, the activity of which is increased in proportion to its own temperature. At the beginning of work the demand for blood flow to the muscles results in reflex vasoconstriction in the skin. As the body temperature rises the thermal demand predominates and the cutaneous vessels dilate, increasing heat conductance to the skin. Large increments in cardiac output and compensatory vasoconstriction in the abdominal viscera make these vascular adjustments in work possible without circulatory embarrassment.

This paper summarizes the factors which influence the energy exchange processes between an individual and his surroundings and the mechanisms by which the body attempts to maintain itself in a heat balance situation. Thereafter, the important physiological reactions to hot working conditions are described and, on this basis, a numerical assessment procedure is proposed. Examples are given of the use of this method in investigating the possibility of heat stress and estimating the time for which an acclimatized worker can safely be exposed in such circumstances. An increase in the permissible exposure time through a manipulation of the environmental parameters is also considered.

Healthcare systems are a very important part of the economy of any country and for the public health. The IoT-based monitoring system for patients with paralysis, which helps to promote the health condition of a patient with paralysis, in addition to the day-to-day life. India has suffered a stroke, the incidence is much higher than that of the more developed countries, it is home to around 2.1 million Indians suffered from the boom of the (lame) per year. If a patient is suffering from a paralysis attack in all or any part of the body can be turned off in order to move in, which means that their movement is restricted and they can barely communicate with anyone at all, because they can't talk like a normal person. Raccoons will find it difficult to understand what they are saying, and help them deal with their day-to-day needs, such as food, water, etc.). At present, work is in progress on the review of the motion parameters on the legs, arms, and head of the paralytics. This paper investigates the development of an integrated and portable prototype is a model of a system for the monitoring of the various movements of the body, spinal cord injuries, with the help of sensors. The tests were carried out by placing the sensors on the head, arm, and leg of the paralyzed patient the data received from these sensors are sent to the raspberry pi 3 model. In the Android app, you'll receive a verbal warning, and if the patient is in need of help via Bluetooth, which, in turn, is connected to the raspberry pi.
