This is a case report of a tracheostomized 80-year-old man suffering from sputum after stroke. His symptoms were watery sputum production requiring frequent sputum suction. The subject was diagnosed as having a deficiency of spleen qi and was treated with Gami-ijung-tang, Yukgunja-tang, Soeumin Bojungikgi-tang, and Ijin-tang extract in the herbal prescription known to dispell Dam-eum (phlegm-retained fluid). Frequency of ssputum suction and condition of sputum were checked everyday. Gamiijung-tang, Soeumin Bojungikgi-tang with Ijin-tang extract led to improvement by reducing sputum secretion. There were limitations on frequency of suction and condition of sputum which were thought to be derived from tracheostomy, however. Consequently, pathology and treatment of sputum will be different whether tracheostomy was performed or not.

본 연구는 한우 난포발달에 있어서 난포액 및 inhibin의 생리적 역할을 검토하기 위해 수행되었다. Anti-inhibin serum(AI)생산을 위해 사용된 항원은 porcine inhibin-$\alpha$-subunit 19~32의 peptide를 사용하여 adjuvant 용액을 혼합, 앙고라종 토끼 5두(체중 2.5kg)에게 주 2회 간격으로 면역 실시 후 52일째의 토끼로부터 항혈청을 생산하였다. 과립막 세포의 체외배양을 위해 D-MEM(10% FCS와 antibiotics를 첨가)을 배양액으로 하여 1$\times$$10^{6}$ cells/$m\ell$로 조절하였으며, 호르몬은 RIA 및 ELISA법으로 분석하였다. Western blotting법에 의해 과립막 세포 및 황체조직의 각 세포질을 SDS-PAGE로 분리하여 nitro cellulose membrane에 transfer하여 검토한 결과, 직경 1.0 cm의 성숙 난포의 granulosa cell의 세포질에서 특이하게 Inhibin이 존재하고 있음이 확인되었으나, 황체조직 및 성숙 난포에서는 검출되지 않았다. 난포 크기별 난포액의 progesterone 및 estradiol-17$\beta$을 농도를 분석한 결과, estradiol-17$\beta$농도는 난포 크기가 직경 2.0 cm부터 유의적으로 높았으나 난포 크기가 적을수록 감소되었다. 이에 반해, Progesterone 농도는 직경 2.0 cm 난포에서 가장 높았으며 난포 크기가 적을수록 낮았다. 과립막 세포의 48시간 체외배양에서 bFF 5% 처리구와 bFF 5%+AI 5% 처리구에서는 progesterone은 대조구보다 유의적으로 억제되었으나, AI 5% 단독 처리구에서는 대조구와 큰 차이가 없었다. 또한, estradiol-17$\beta$농도는 5% AI구와 5% AI+5% bFF 처리구에서는 대조구에 비해 증가하였다. 그러나, 5% bFF 단독처리구에서는 대조구와 큰 차이가 없었다. 이상의 결과로, 한우에 있어서 성숙난포에 존재하는 Inhibin은 AI처리에 의해 내인성 Inhibin의 기능이 약하되어 FSH분비를 조절하는 역할을 함으로써 난포발달 및 난포세포의 스테로이드호르몬합성에 중요하게 관여하고 있는 것으로 사료된다.

Male accessory glands and ejaculatory duct of Drosophila melanogaster are reproductive organs which synthesize secretory seminal proteins. Several products of these organs involved in egg laying, receptivity, and sperm stability or storage were isolated from their lumens. Despite their secretory process play an important role, exocytosis pathway in these organs is not well known. In the present study, we characterized secretory protein profiles and determined their secretory mechanisms. Eight accessory gland secretory proteins and two ejaculatory duct secretory proteins were detected in their lumens. All these proteins were constitutively synthesized in these organs and secreted to their lumens. Secretion of newly synthesized proteins initiated at about 1 h after synthesis, and reached the peak at 4 h after synthesis. It seems that secretion of the proteins may occur via constitutive exocytosis pathway.

A sialocele is a subcutaneous cavity containing saliva, most often caused by facial trauma or iatrogenic complications. In subcondylar fractures, most surgeons are conscious of facial nerve injury; however, they usually pay little attention to the parotid duct injury. We report the case of a 41-year-old man with a sialocele, approximately $5{\times}3cm$ in size, which developed 1 week after subcondylar fracture reduction. The sialocele became progressively enlarged despite conservative management. Computed tomography showed a thin-walled cyst between the body and tail of the parotid gland. Fluid leakage outside the cyst was noted where the skin was thin. Sialography showed a cutting edge of the inferior interlobular major duct before forming the common major duct that seemed to be injured during the subcondylar fracture reduction process. We decided on prompt surgical treatment, and the sialocele was completely excised. A duct from the parotid tail, secreting salivary secretion into the cyst, was ligated. Botulinum toxin was administrated to block the salivary secretion and preventing recurrence. Treatment was successful. In addition, we found that parotid major ducts are enveloped by the deep lobe and extensive dissection during the subcondylar fracture reduction may cause parotid major duct injury.

It has long been suggested that the cardiac atrium is a low pressure volume receptor controlling body fluid volume and blood pressure. Recently, the cardiac atrium has been found to contain a family of powerful peptides. To clarify the relationship between high blood pressure and the biologically active atrial peptides, experiments were done to define the characteristics of atrial natriuretic peptide secretion in the isolated perfused atria of renal hypertensive rats. Higher concentrations of plasma atrial natriuretic peptide and renin activity were observed in the two-kidney, one clip hypertensive rat compared to the normotensive rat. Atrial volume changes in response to pressure elevations were attenuated in hypertensive rats compared to normotensive rats. Incremental response to atrial volume changes in ANP secretion was accentuated in hypertensive rats. These date suggest that the accentuated atrial natriuretic peptide response to volume changes of hypertensive rats may be a physiological or pathphysiological adaptation to the high blood pressure and may be, at least in part, responsible for the elevated levels of plasma atrial natriuretic peptide observed in hypertensive rats.

Previously, we have reported that ${\rho}-chlorophenylalanine$ (PCPA), a serotonin depletor, profoundly increased pancreatic fluid and bicarbonate secretion but remarkably inhibited pancreatic amylase secretion in anesthetized rats. The present study was performed to verify the detailed effects of PCPA on pancreatic amylase synthesis that is directly related to amylase exocrine secretion. PCPA significantly decreased pancreatic RNA and protein contents as well as the amylase activity. However, pancreatic DNA content, trypsin and chymotrypsin activities were not influenced by the treatment of PCPA. The rate of pancreatic amylase synthesis, which was assessed by the amount of incorporated $[^{35}S]-methionine$ into amylase for 1 h, was also significantly decreased by 44% in PCPA-treated rats. In order to determine whether the PCPA-induced decrease of amylase synthesis resulted from change in the level of amylase mRNA, Northern blot analysis was performed. The mRNA expression level of amylase was also decreased by 48% in the PCPA-treated rats, indicating that the inhibitory effect of PCPA on the synthesis of pancreatic amylase was mainly regulated at a step prior to translation. It was also revealed in SDS-polyacrylamide gel electrophoresis that the qualitative change of amylase was induced by PCPA. The 54 KDa amylase band seems to be degraded into small molecular weight protein bands in PCPA-treated rats, suggesting that the PCPA- induced decrease of amylase may be partly attributed to the degradation of synthesized amylase.

돼지난포란의 체외성숙, 체외수정 및 체외 배양체계의 개발은 핵치환에 의한 복제동물 및 형질전환 동물생산 등과 같은 첨단생명공학연구 추진에 크게 기여할 것이다. 그러나 돼지난자의 체외수정시 다정자 침입은 큰 문제점으로 지적되고 있는데, 그 원인 및 개선책은 많은 연구에도 불구하고 정확히 밝혀져 있지 않다. 따라서 본 연구는 돼지 난포란으로부터 채취한 난자를 체외성숙 후, 체외수정시 체외수정 배양액에 난관액을 첨가하여 수정율 및 다정자 침입율을 조사하고, 또한 체외수정 후 체외 배 발달율을 조사할 목적으로 실시하였다. 수정용 배양액에 1과 5% 난관액을 첨가하였을 때 정자침입율과 수정시 난자에 침입한 정자의 평균 수가 감소하였으며, 또한 투명대에 부착된 정자의 수도 감소하였다. 난관액이 첨가된 수정용 배양액에서 정자를 1.5와 3시간 동안 전 배양을 실시하였을 때 정자의 수정능 획득과 첨체반응이 대조군에 비해 증가되었다. 그리고 1% 난관액이 포함된 배양액에서 체외수정된 난자의 배반포까지 발달율은 18.9%로 대조구의 12.4%보다 유의성 있게 높았다. 이러한 연구결과는 난관 분비액의 어떤 인자가 정자의 첨체반응을 유도해서 정자침입율 및 다정자 침입을 감소시키고, 이어 배발달율을 증가시킨다고 사료된다.

본 실험은 생쥐에서 부정소액내의 단백질 성분과 조성에 미치는 정소액과 정자의 영향을 알아보기 위하여, 성적 성숙시기에 따라 정소와 부정소의 조직분화 양상을 관찰하였으며, 강소분화 특징에 따라 체취한 부정소액은 전기영동법으로 단백질을 분석하여 다음과 같은 결과를 얻었다. 정소와 부정소는 생후 10일군에서 미분화 상태였고, 20일군에서 세정관의 강소는 형성되지 않았으나 부정소는 두부에서 미부에까지 강소가 형성되었으며, 35일군에서는 정소내 세정관의 강소가 형성되었고 정세포는 정자로 분화되었고, 부정소의 상피세포는 principal cell과 clear cell로 분화되었으나 부정소로 유입된 정자는 없었다. 80일군에서는 정소와 부정소가 완전히 본화되었고 부정소로 유입된 많은정자가 관찰되었다. 그리고 부정소액의 전기영동상에는 혈청내의 성분과 다른 단백질이 모두 28종이 나타났는데, 그 중 12종은 부정소액에만 존재하는 부정소 특이단백질이었고, 16종은 정소액에도 공통으로 존재하는 단백질이었다. 또한 이 단백질들은 성숙시기에 따라 종류가 다르게 나타났으며, 성체에서 나타난 3종의 단백질은 부정소의 부위에 따라 양적인 변화를 나타냈다. 이상의 결과로 보아 부정소액내 단백질의 성분과 조성은 정자를 포함한 정소액의 유입과 부정소 상피세포의 분비 및 흡수의 조절작용에 의하여 변화되는 것으로 사료된다. 따라서 부정소액내의 TEP와 ESP는 부정소 정자의 성숙에 어떤 중요한 역할을 할 것으로 사료된다.

The experiments were carried out to study the effect of physical forms of hay diet on phosphorus metabolism by offering sheep roughage diets containing a low phosphorus content. The sheep were fed coarse hay, short hay or finely ground pelleted hay. The physical forms of hat diet had little effect on the pathway of phosphorus excretion. In all groups, the most of phosphorus was excreted in feces and urinary phosphorus excretion was negligible. Duodenal fluid flow, rumen fluid outflow and estimated salivary flow appeared to be relatively high in sheep fed the coarse hay diet as compared to those in sheep fed the finely ground diet. The amount of phosphorus flow to the duodenum tended to be high in the coarse diet group as compared to those in other two groups. On the other hand, phosphorus concentrations in the duodenal fluid and the rumen fluid were lower in sheep fed the coarse hay diet than those in sheep fed the ground hay. Net intestinal phosphorus absorption tended to be higher in sheep fed the coarse hay than that in sheep fed the ground hay or pelleted hay. However, a negative phosphorus balance was observed in the coarse hay diet group although a positive phosphorus balance was found in other two groups. It was considered that salivary phosphorus secretion was greater than the amount of salivary phosphorus reabsorbed from the intestine, resulting in the negative of phosphorus balance in sheep fed the coarse hay.

At the fifth day after right lung pneumonectomy in New-Zealand white rabbits $(0.8{\sim}1.1\;kg\;B.W.)$, phospholipid and protein concentration in the left lung lavage fluid were measured for clarification of the effect of unilateral pneumonectomy on the secretory function of the type II pneumocytes in growing rabbits. In an attempt to evaluate the effect of unilateral pneumonectomy on the compensatory growth of the residual lung, left lung weight and left lung weight-body weight ratio and DNA concentration, RNA/DNA and total DNA content in the left lung tissue were measured in pneumonectomized and in sham operated control rabbits. The lung weight of pneumonectomized rabbit was approximately two times heavier than that of the control rabbits. DNA concentration and RNA/DNA of the lung tissue were not changed but total DNA content was increased significantly. Phospholipid concentration in the lung lavage fluid of the pneumonectomized rabbits was over two times higher than that of control rabbits. from these experimental results, It is concluded that unilateral pneumonectomy in growing rabbits might cause to increase the secretion of pulmonary surfactant from type II pneumocyte of the residual lung. The cellular hyperplasia seems to be the primary response of the compensatory growing lung in unilateral pneumonectomized growing rabbits.
