Acting on the theory that hyperpyrexia is the effective agent in the treatment of general paralysis by malaria, Neymann and Osborne (1) experimented on dogs to see whether, by means of diathermy, sufficient heat could be generated to raise the temperature of the experimental animals to a high degree without injurious results.This being found practicable, they devised a method of applying diathermy to the human subject, with the same purpose in view.They found that they were able, by using a suitable set of electrodes, and by thorough insulation of the individual, to raise the body temperature to any height, and, moreover, to keep the temperature under definite control.

Current assumptions concerning body temperature of experimental animals, particularly as it relates to the selection of caloric test stimuli, are likely to be inaccurate guesses. Although the temporal bone of squirrel monkeys attenuates irrigation temperature by a factor of nearly 10, there is a high correlation between thermal changes in inner ear fluid and irrigation values. In this study, nystagmus (defined by electronystagmographic thresholds) occurred when horizontal canal temperatures deviated from resting temperature by ±0.14 C.

The study focused on the effect of microwave radiation at a dose which commonly does not lead to tissue heating, however, in the rat testes it resulted in accumulation of heat. Adult rats were exposed to whole body pulse radiation at a frequency of 2.45 GHz and mean power density of 28 W/m2, for 3 h a day for the duration of 3 weeks. Immediately after each irradiation, the body temperature and the testicular temperature were measured in the control and experimental animals. Samples for histological and immunohistochemical analysis were taken after the last irradiation and processed for light and transmission electron microscopy. An evaluation of spermatozoa motility was performed using computer-assisted sperm analysis. Although the body temperature of the rats was not elevated after the irradiations, the testicular temperature was significantly increased (P < 0.004). Testes of the experimental animals had considerably dilated and congested blood vessels and the seminiferous epithelium showed degenerative changes. The Leydig cells showed no obvious structural abnormalities. Transmission electron microscopy revealed ultrastructural changes in developing sex cells, Sertoli cells, and endothelial cells. An intensified immunoreactivity to superoxide dismutase 1 was found in spermatogonia and Leydig cells in the experimental animals. Results of the present study revealed a distinctly adverse effect of microwave radiation on the thermoregulatory capability and histological structure of rat testes as well as an oxidative damage of the tissue. The scientific knowledge confirming or denying the thermal effect of microwave radiation on living tissue is scarce and thus the present study may be regarded as unique and helpful to clarify the issue.

Peranakan Etawa (PE) goat farming is one of the growing livestock sectors in Indonesia. Indonesia needs a sustainable breeding system that can guarantee the availability of goats. Estrus synchronization is a necessity that can help uniform the breeding time and manage the time of pregnancy and birth. Artificial estrus synchronization techniques that use a combination of Prosterone and Zinc minerals give good results of estrus synchronization in goats. The Aim of this research is to understand the combination efectiveness of estrus synchronization technique with progesterone acetate and Zinc supplementation. The design of this study used two treatment groups, each group consisting of three does PE goats. Estrus synchronization of experimental animals in treatment 1 and 2 was carried out using polyurethane sponge implant method which contained medroxi progesterone acetate 60 mg. Group 1 was given Sponge Progesterone for nine 9 days while giving Zinc (Zn) mineral supplement (Elemental Zn 20 mg, Kimia Farma) orally given 7 times. The frequency of Zinc administration every day begins during intra vaginal sponge insertion. Group 2 was treated same as group 1 with 14 days of implant time and 7 times of Zinc supplementation.The results showed that both treatments occurred estrus simultaneously with good estrus quality. Both treatments show the results of the estrus 8 score assessment with the estrus 3-9 range. The maximum estrus quality’s value of group 2 was higher (8.33 ± 0.57) compared to group 1 (8.0 ± 1.0). The estrus duration of group 2 occurs for 24 hours and group 1 for 7 hours. Estrus onset of Group 2 is earlier (58 hours) than group 1 (75 hours). Both treatment groups showed an increase in temperature at period of the occurrence of estrus. Body temperature during estrus time was 38.7 ± 0.20 0C to 39.60 ± 0.26 0C. The conclusion of this study is that in both treatments of estrus synchronization using sponge progesterone and zinc supplementation can cause estrus synchronization effectively . The duration of estrus in group 1 (9 days of implant) was Shorter than group 2 (14 days of implant). The onset of estrus time of group 1 (9 days of implant) was longer than Group 2 (14 days of implant). The body temperature of the experimental animals increases with the occurrence of estrus.
