Objectives : To investigate the effect of Taxilli Ramulus (TR) extract on bone metabolism of ethanol-treated animal model. Methods : The changes of serum calcium, calcitonin, estrogen level, a1ka1ine phosphatase activity, osteocalcin, parathyroid hormone content and urine calcium level were observed with ethanol treatment for 60 days. The results were compared with an ethanol- TR extract double treatment group. Results : We observed increment of serum osteocalcin, parathyroid hormone content, alkaline phosphatase activity and urine calcium level by chronic ethanol feed and they were recovered to near normal level with Taxilli Ramulus extract treatment. Weight gain, serum calcium level, calcitonin and estrogen content were remarkably reduced with ethanol treatment and their levels were normalized by Taxilli Ramulus extract. Conclusions : These results showed that Taxilli Ramulus extract have the ability to recover to normal in the body an abnormal calcium metabolism process due to external factors. These results suggested that Taxilli Ramulus extract have preventive effects on calcium concentration loss and osteoporosis.

The relationship between acute pancreatitis and hyperparathyroidism has been described extensively in the past. Despite the rarity, the clinical progression of pancreatitis associated with hyperparathyroidism has been known to be so rapid and severe that it may cause death. When, furthermore, the pancreatitis is caused by hyperparathyroidism, the recovery from disease can be hardly expected unless the hyperparathyroidism is corrected. We present a case of acute pancreatitis in a 68-year-old man that have been caused by primary hyperparathyroidism. The clues of hyperparathyrodism were hypercalcemia and elevated parathyroid hormone, but he showed subtle or negative symptoms of hypercalcemia. After the excision of parathyroid adenoma, serum calcium level returned to normal and the symptoms and function of pancreas were recovered.

Recombinant human pBrathyriod hormone related peptide (1-341 (rhPTHrP) has been known to stimulate bone resorption in intact bone tissue culture system. Osteoclast has been known as a primary responsible cell for bone resorption. To examine the effect of rhPTHrP on this cell, we employed disaggregated rat osteodast culture. As a result, we found that rhPTHrP sisnificBntly elevates both the number and total area of resorbed pits in this culture. On the other hand, the conflicting results between disagsregated rat osteoc13st culture and Ca2+-deficient hen osteoclast culture system have been a big obstacle for the progress of bone research. To verify the differences between rat 3nd chick osteoclast system, we performed the same experiment using chick embryonic osteoclast. Since the similar results were obtained from the disaggregated chick osteoclast culture, the discrepancy between chick and rat osteoclast culture study seemed to be due to the difference in culture method, rather due to the species-difference.

Objectives : This study was undertaken to study the action mechanism of Rhizoma Davalliae (RD) at parameter related to regulating bone density. Methods : We measured alkaline phosphatase activity and the contents : calcium, hydroxyproline, osteocalcin, calcitonin, and parathyroid hormone after the ovariectomized rats had been treated with RD for 30 days. Results : The following changes occurred: First, the serum calcium content and the calcitonin content, which decreased in ovariectomized rats, increased with RD treatment. Second, the serum alkaline phosphatase activity, the parathyroid hormone ativity, the osteocalcin content, the urinary calcium content, and the hydroxyprolin content-which increased in ovariectomized rats-decreased with RD treatment. Conclusions : These results show that RD treatment can recover abnormal calcium metabolic process by sex hormone inequality, promoting bone formation and inhibiting bone absorption.

Granular cell tumor is an uncommon neoplasm that can occur everywhere in the human body. Granular cell tumor of the cervical esophagus is rare. Histopathologically, granular cell tumor consists of large polygonal cells with small dark nuclei and abundant, fine, granular eosinophilic cytoplasm that show positive immunohistochemical staining using S-100 protein. Surgical excision is the treatment of choice for granular cell tumor. Recurrence is rare, but inadequate resection of granular cell tumor may cause local recurrence. We have experienced one case of granular cell tumor of the cervical esophagus that was misdiagnosed with parathyroid tumor. Therefore, we report it with the literature review.

Pseudohypoparathyroidism (PHP) is very rare and shows heterogeneity with impaired genetic components. PHP is characterized by parathyroid hormone resistance to target organ, related with a GNAS (guanine nucleotide-binding protein α-subunit) mutation and epimutation. PHP receptor is coupled with the stimulatory G protein which activates cyclic adenosine monophosphate formation. PHP type 1A is caused by inactivating mutations on the maternal allele of the GNAS whereas paternal allele mutations cause pseudopseudohypoparathyroidism. PHP type 1B is caused by abnormal patterns of methylation in differentially methylated region which can be divided into partial or complete. This disease has some difficulties to diagnose according to these different molecular alterations caused by complex genetic and epigenetic defects. According to this different molecular alterations, genetic confirmation must be done to discriminate their etiology.
