The effects of the erect bipedal stance exercise on bone mass and the biomarkers of bone formation and resorption were investigated in rats. Five-week old rats were assigned into control and exercise groups. The rats of exercise group were weight-bearing-trained for 13 weeks in the cage designed to adjust progressively the height from 26.5 cm to 31.5 cm to force the rats rising an erect bipedal stance for feeding and drinking. There was no significant difference in food intakes between two groups. But body weight gain was significantly increased in control group. The lengths of femur, tibia, humerus and radius were significantly longer in control group than exercise group, but the femur and tibia weights per body weight were significantly higher in exercise group than control group. Also the breaking force of femur and tibia in exercise group were higher than control group significantly. The calcium contents of femur and tibia were significantly increased in exercise group than control group. The activity of bone specific alkaline phosphatase (B-ALP) and the osteocalcin contents of serum (the biomarkers of bone formation) in exercise group were higher than control group, but the carboxyterminal propeptide of type I procollagen (P1CP) contents of serum did not show any difference between two groups. However the urinary deoxypridinolin (DPD) excretion, biomarker of bone resorption, was significantly lower in exercise group than control group. From these results, it has been indicated that the erect bipedal stance exercise enhanced the density and the strength of femur and tibia by increasing biomarkers of bone formation and suppressing a biomarker of bone resorption in rats.

This study wa performed to investigate the effects of dietary protein and fiber on the lead and protein metabolism in lead poisoning rats. Seventy male rats of Sprague-Dawley strain weighing 172$\pm$2g were blocked into 14 gropus according to body weight. Protein(casein) was given at levels of 15 or 40%, and fibers(pectin, cellulose and CMC) were given at levels of 0, 4 or 10%. The results are summarized as follows: 1. Food intake, weight gain and food efficiency ratio(FER) in groups fed high protein diets were higher than those in low protein groups. Liver weight in groups fed no dietary fiber was higher than that of animals fed fiber. Kidney and femur weights were greater in high protein groups. Tibia and femur lengths, and tibia weight were not significantly different among groups. 2. Hemoglobin content and hematocrit values showed no significant differance with dietary factors. 3. Total protein contents of serum and liver showed no significant difference, but tended to increase with increasing dietary protein level. Both daily urinary and fecal nitrogen excretions in high protein groups were higher than those in low protein groups. Especially daily fecal nitrogen excretions in high dietary fiber groups were significantly high. Body nitrogen absorption rate was the highest in animals fed no fiber. 4. Pb levels in blood, liver, kidney and bone tended to decrease with high dietary protein and fiber levels. Especially Pb level of kidney was high in all groups. Daily urinary Pb excretion showed no significant difference with dietary factors, but fecal Pb excretion increased significantly in high protein and fiber groups.

The anatomical structure of pelvic limb, of thirty-one adult Korean native goats (Body weight: 14~17kg) was observed after skeletal preparation, and the osteometry was performed in each bone. The results were as follows: 1. The pelvic limb of the Korean native goat was composed of the hip bone, femur, patella, tibia, fibula, tarsal bones, metatarsal bone, phalanges and sesamoid bones. 2. The hip bone consisted of the ilium, ischium and pubis which fused each other, The gluteal surface of the ilium was directed dorsolaterally. The tuber sacrale and tuber coxae were formed at the dorsal apex and ventrolateral part of the iliac wing, respectively. The lesser ischiatic notch was deeper than the greater one. The ischiatic tubercles were triangular form and consisted of the dorsal, lateral and caudal ischiatic tubercles. The left and right hip bone indexes were 67.08, 66.20, the acetabular indexes were 93.78 and 92.10 and the obturator foramen. indexes were 53.84 and 54.77, respectively. 3. In femur, both of the greater and lesser trochanter were well developed but the third trochanter was not observed. The left and right femur indexes were 26.55 and 26.14, head indexes were 81.66 and 81.49 and the trochlear-epicondyle indexes were 42.47 and 41.63, respectively. 4. The patella was observed as an isosceles triangle with base lying proximal and the cranial surface was more convex. 5. The tibial shaft was sigmoid form and the popliteal notch was deep. There was a large nutrient foramen at the cranial aspect of the cranial intercondylar area. The tibial indexes were 22.09 in left and 21.10 in right. 6. The proximal extremity of the fibula was fused with the lateral condyle of the tibia but the distal one was observed independently as the malleolar bone. 7. The tarsal bones were five in number; the talus, calcaneus, centroquartal tarsal bone, first tarsal bone, and second-third tarsal bone. 8. The metatarsal bone was composed of a large metatarsal bone. resulted from the fusion of the third and fourth metatarsal bones, The structure of metatarsal bone was similar to the metacarpal bone but longer about 7mm. 9. The phalanges and sesamoid bones were similar to these of the thoratic limb. 10. The ratios of the lengths among the hip bone, femur, tibia and metafarsal bone were 1.71 : 1.54 : 1.73 : 1.00 in left and 1.68 : 1.53 : 1.72 : 1.00 in right, respectively.

말차, 오룡차, 홍차 및 보이차로 제조한 음료가 Cd에 중독된 SD계 흰쥐의 해독에 미치는 영향을 조사하였다. 관능검사 결과 일반 물 추출물에 비하여 색상, 향, 맛에 대한 기호도가 현저하게 향상되었으며, 종합적 기호도는 오룡차 음료가 4.18점, 홍차음료가 4.14점으로 말차음료나 보이차 음료의 $3.74{\sim}3.88$점에 비하여 높았다. SD계 흰쥐를 정상군 (NC), Cd 대조군(Cd-Co), Cd투여 말차음료 15% 급여군 (Cd-Gt), Cd투여 오룡차음료 15% 급여군(Cd-Ot), Cd투여 홍차음료 15% 급여군(Cd-Bt) 및 Cd투여 보이차음료 15% 급여군 식이군(Cd-R)의 6군으로 구분하여 5주간 사육하였다. 차 음료 식이군의 체중증가량은 NC군에 미치지는 못하였으나 Cd에 의하여 감소된 현상을 상당히 개선하였다. 식이효율, 뇨량 및 분변량은 각 실험군간의 유의적인 차이가 없었다. Cd의 투여는 간과 신장의 중량, 경골의 중량 및 대퇴골의 길이를 감소시켰으나 차 음료의 섭취로 다소 개선되었다. 혈청 AST 및 ALT 활성은 모두 Cd 투여군에서 현저하게 증가하는 경향을 보였으나 차 음료 급여군에서는 5%수준에서 유의적으로 감소되었다. 대퇴골의 조회분 함량은 Cd-Co군에서 40.72%, Cd 투여-차 음료 급여군에서는 $35.31{\sim}37.02%$로 차음료의 급여에 의하여 5%수준에서 유의적으로 감소하였다. 대퇴골의 조회분 함량은Cd-Co군에서 40.72%, Cd 투여-차 음료 급여군에서는 $35.3{\sim}37.02%$로 차음료의 급여에 의하여 유의적으로 감소하였다 대퇴골의 Cd함량은 NC군에서는 0.08 ppm이었으나 Cd-Co군은 123.28 ppm, 실험식이군에서는 $23.07{\sim}28.82 ppm$으로 차음료의 급여로 현저하게 감소하였으며, Ca 함량은 NC군에서 6700 ppm, Cd-Co군에서 3760 ppm, 실험식이군에서는 $4040{\sim}5420 ppm$이었다. 분변의 회분함량은 Cd-Bt군이 14.80%로 높았으나 기타 음료군은 Cd-Co군과의 유의적인 차이를 보이지 않았다. 분변의 Cd 함량은 NC군 0.02 ppm, Cd-Co군 2.06ppm, 실험식이군 $4.38{\sim}5.35ppm$로 차 음료 급여군에서 높았으며, 이와 대조적으로 Ca함량은 차음료 급여군에서 낮았다. 이상의 실험결과, 말차, 오룡차, 홍차 및 보이차로 제조한 음료는 상호간의 뚜렷한 차이는 없으나 모두 섭취한 Cd를 체외로 배설시킴으로서 Cd에 의한 장기 손상을 경감시켜 줄 수 있을 것으로 생각된다.
