Body surface areas (BSA) of 31 apparently normal rhesus monkeys of both sexes weighing 3.2–5.3 kg were determined by the direct skinning technique. The range of measured BSA was 1,940–3,020 cm2 (mean = 2,430 cm2). The BSA values of male and female monkeys were not significantly different. The K value, calculated as the ratio of BSA (cm2)/body wt2/3 (kg), was 969 +/- 15 (SE). Based on the principle of least squares for goodness of fit between the measured and calculated BSA, the best equation was determined to be (see article). A nomogram was constructed for rapid determination of the BSA of rhesus monkeys with known body weight and lengths (head to anus). Monkey BSA could also be computed by multiplying the DuBois human BSA equation by a factor of 1.147 for the head-to-anus measure of length or by 0.891 for the head-to-heel measurement.

The present study was conducted to determine the early sex in turkeys by observation of the differences in body weight between male and female birds. A total of 30-day old black color unsexed poults having almost similar body weight at hatching were considered for the experimentation and housed at the Poultry Farm of Bangladesh Agricultural University, Mymensingh-2202, Bangladesh. All birds were reared up to 12 weeks of age under intensive management with supplementation of commercial broiler starter and grower feeds. Birds were reared under similar management conditions. Significantly higher (p<0.01) body weight was attained in male poults (104g/bird) than the female (90g/bird) at the end of 1st week of age. Similarly, at the end of 2nd week of age higher (p<0.01) body weight attained by male poults (198.31g/bird) than the female (162.13g/bird). At the end of 3rd weeks of age male poults attained higher (p<0.01) body weight (307.23g/bird) than the female (251.33g/bird). After 4 weeks of rearing, male turkeys attained significantly higher (p<0.01) live body weight (424.46g/bird) than the female turkeys (347.87g/bird). The weekly average body weight gains of male and female birds were 94.18g/bird and 76.5g/bird, respectively. Thus, the male and female birds were successfully identified on the basis of differences in their body weight. Weekly feed intake for both the male and female birds was also increased with their age. Up to 4 weeks of age, both the male and female poults consumed same amount of feed (753.46g/bird). The FCR of male and female poults differed non-significantly in 1st, 3rd and 4th week. On the contrary, in 2nd week of age the FCR of male poults (1.60) was significantly lower (p<0.01) than female (2.11). Survivability was 100% up to 4th week of age irrespective of sex of the poults. The birds were reared up to 12 weeks of age until to confirm their sex by observation of the phenotypic appearance. Results of the phenotypic observation of male and female birds correspondence hundred percent accuracy with the results obtained in body weight based differences between male and female birds. It is therefore concluded that farmers can identify male or female poults as early as first week of age on the basis of body weight differences. Progressive Agriculture 31 (3): 218-226, 2020

Transthoracic Resistance

Transthoracic impedance is a major determinant of successful defibrillation or cardioversion, but no data are available concerning the range and determinants of transthoracic impedance in children. Transthoracic impedance was measured in ten ambulatory infants, 6 weeks to 9 months of age, and 37 children, 1.5 to 15 years of age, using a previously validated "test pulse" technique that measures transthoracic impedance without actually delivering a shock. We used hand-held "pediatric" (21 cm2) and "adult" (83 cm2) electrode paddles coated with either Redux paste or Redux creme. Transthoracic impedance in children was 108 ± 24 Ω (range 61 to 212 Ω) using pediatric paddles. Using adult paddles lowered the transthoracic resistance by 47% to 57 ± 11 Ω (range 29 to 101 Ω), P &lt; .05. In infants, transthoracic impedance (measured only with pediatric paddles) was 94 ± 17 Ω (range 74 to 124 Ω). Using Redux paste as the coupling agent reduced transthoracic impedance by 13% (P &lt; .05). Transthoracic impedance was significantly but poorly related to body weight and body surface areas, but the correlations were not sufficiently high to be clinically useful. These data indicate that the larger adult electrode paddles will minimize transthoracic impedance and should be used when the child's thorax is large enough to permit electrode to chest contact over the entire paddle surface. This transition occurred at an approximate weight of 10 kg.

Series Of Experiments

In the course of investigations on the production, distribution, and rate of disappearance in the body of immune substances, we were occupied in 1908 and previous years with a series of experiments on agglutinins, and we arrived at conclusions pointing to their close relationship to the blood and blood-forming organs (1, 2). In association with these inquiries, one of us (G. D.), together with W. Ray, published a communication on the relation­ship between the blood volume and the distribution of agglutinins within the circulation (3). It was there shown that the concentration of this substance (agglutinin) in the blood after inoculation into an animal was proportional to the body surface of the animal concerned, and was thus approximately proportional to the two-thirds power of the weight. Hence was deduced the conclusion that the blood volume of the animals examined was proportional to their body surface.

Kidney Length

Objective: To determine the normal range of kidney length and volume in term Bangladeshi newborn. Methods: Hundred inborn, healthy, appropriate for gestational ages, term infants were prospectively examined by sonography within 72 hours of birth by a single senior sonologist. In 52 boys and 48 girls body weight (BW), supine length (SL), occipito frontal circumference(OFC) were collected from delivery room records, and body surface area (BSA) was calculated using the formula BSA=BW(kg)0.425 ×BL(cm)0.725 ×0.007184 and BMI=Weight(kg)/height(m)2. Scanning was performed with 6.5 MHZ transducer with child supine position. Maximum length of each kidney was determined. Volume of the kidney was determined by the inbuilt formula of software. Kidney length and volume were then correlated with gestational age, body weight, length, OFC, body mass index (BMI) and body surface area of infant. Results: There were no significant differences in mean kidney length and volume between right (39.22±4.32 mm, 9.79±2.80cc) and left (38.36±4.30 mm, 9.82±2.24cc) and kidneys in boys (right kidney 39.77±4.28mm, 10.30±2.69cc, left kidney38.62±3.68mm, 9.91±2.06cc) and girls (right kidney 38.63±4.32mm, 9.23±2.83cc left kidney 38.09±4.91mm, 9.73±2.43cc). Kidney length was correlated better with BMI (<0.001), BW (<0.01) and BSA. (<0.05). Kidney volume was also correlated with BW (<0.05), BMI (<0.05) and BSA (<0.05). No correlation found with length and OFC. Conclusion: The present study provides an important baseline data in term babies for kidney dimension in Bangladeshi neonate.

Abstract Objective Dogs are a breed of animals that play important roles in security service, companionship, hunting, guard, work and models of research for application in humans. Intelligence is the key factor to success in life, most especially for dogs that are used for security purposes at the airports, seaports, public places, houses, schools and farms. However, it has been reported that there is correlation between intelligence, body weight, height and craniometry in human. In view of this, literatures were searched on body weight, height and body surface areas of ten dogs with intent to determining their comparative level of intelligence using encephalization quotient. Results Findings revealed that dogs have relationship of brain allometry with human as proven by encephalization quotient $$\left( {{\text{EQ}}} \right)\, = \,{\text{Brain Mass}}/0.{14}\, \times \,{\text{Body weight}}^{{0.{528}}} ,{\text{ Brain Mass}}/0.{12}\, \times \,{\text{Body Weight}}^{{0.{66}}}$$ EQ = Brain Mass / 0.14 × Body weight 0.528 , Brain Mass / 0.12 × Body Weight 0.66 and Brain Mass (E)  =  kpβ, where p is the body weight; k  =  0.14 and β = 0.528, respectively. Saganuwa’s formula yielded better results as compared with the other formulas. Dogs with body surface area (BSA), weight and height similar to that of human are the most intelligent. Doberman pinscher is the most intelligent followed by German shepherd, Labrador retriever, Golden retriever, respectively.

A radioimmunoassay for the determination of concentrations of melatonin in the plasma of rhesus monkeys has been developed. Antiserum for the assay was raised against N-acetyl serotonin and there was a 100% cross-reaction with melatonin. Cross-reactivity with closely related indoles, precursors and metabolites was less than or equal to 1%. The lower limit of sensitivity of the assay was 4 pg/tube. The assay has been used for the investigation of diurnal variations and cyclical changes in melatonin concentrations in peripheral plasma of the rhesus monkey. The concentrations of melatonin ranged between 26·6 and 85·3 pg/ml during sampling for 24 h.There was a distinct diurnal variation in the concentration of melatonin in plasma. The concentration during darkness (61·0 ± 7·1 (s.e.m.) pg/ml) was greater (P <0·01) than that during illumination (40·1 ± 6·1 pg/ml). There were no significant differences in the concentration of melatonin in plasma at any time during the 28 day menstrual cycle of the rhesus monkey.

Herpes-like viruses were isolated from rhesus monkey peripheral blood leucocytes when co-cultivated with WI-38 cells. The virus was originally designated rhesus leucocyte-associated herpesvirus (LAHV) and subsequently called Herpesvirus mulatta (HVM). The original isolations were from juvenile rhesus monkeys shown to be free of antibody to rhesus cytomegalic virus. The virus could only be propagated in human or simian fibroblasts. Use of specific antisera developed from HVM showed no relationship between this virus and other herpesviruses. An electron microscopic study was undertaken to determine the morphology of Herpesvirus mulatta (HVM) in infected human fibroblasts.
