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.

This study was performed to investigate the effects of the peptide to carrier ratio on the immune and biological functions to inhibin immunization in Hanwoo. A peptide sequence kom the alpha -subunit (19~32 peptide) of porcine inhibin was synthesized for antigen and conjugated to human serum albumin(HSA) for carrier protein. Anti-inhibin sera(AI) were produced 52 day later from rabbit after injection of inhibin-$\alpha$ -subunit peptide conjugator for antigen with the interval of 2 weeks. Immune-blotting analysis using antibody specific fur inhibin-$\alpha$ subunits revealed that the inhibin was detected at 1.0 cm bovine follicular fluid(bFF). However, each stage of corpus lutea and 0.1 cm of follicular fluid were not detected. The maximal contents of estradiol-17 $\beta$ in Hanwoo ovarian follicular fluid were detected at 2.0 cm of follicular size(diameter), but the mean total contents of these hormone decreased significantly with decreasing diameter of follicles. However, progesterone contents of follicular fluid were high at 1.0 cm of follicle. Progesterone secretion by Hanwoo granulosa cell cultured for 48 hr in vitro was significantly (p＜0.05) inhibited in 5% bFF and 5% bFF + 5% AI addition group compared with control group. Estradiol-17 $\beta$ secretion by Hanwoo granulosa cell cultured for 48 hr in vitro was significantly (p＜0.05) increased in 5% AI and 5% AI + 5% bFF addtion group compared with control group. However, the groups added 5% AI were not changed compared to control groups in progesterone and estradiol-17 $\beta$. Taken together, we suggested that inhibin in the mature FF plays a pivotal role on the biosynthesis of steroid hormone of follicular cells during follicular development.

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.

The objective of this study was to determine effects of oviductal fluid on the sperm penetration and subsequent in vitro development of porcine oocytes. The addition of oviductal fluid to the fertilization medium decreased sperm pen etration and the mean number of spermatozoa in penetrated eggs. The number of spermatozoa firmly bound to zona pellucida was also decreased in the presence of oviductal fluid. Chlortetracy cline (CTC) fluorescence patterns were used to determine incidence of capacitation and acrosome reaction. The proportion of capacitated a and acrosome free spermatozoa increased when spermatozoa were exposed for 1.5 and 3 h to oviductal fluid. These results suggest that the factor(s) in secretion from the oviduct reduces polyspermic fertilization and the number of spermatozoa that will penetrate porcine oocytes. The reduction of polyspermic penetration by oviductal secretions may be due to a reduced number of spermatozoa in the fertilization me-dium into an intact acrosome.

In order to study the influence of spermatozoa and testicular fluid on the component and composition of proteins in epididymal fluid of mice, histological differentiation of testis and epididymis were observed during sexual maturation, and the proteins in epididymal fluids collected according to the characteristics of lumination were analyzed by electrophoresis (SDS-PAGE). In 10 day-old mouse, both of,testis and epididymis were undifferentiated. In 20 day-old mouse, epididymis was primitively luminated, but testis was not. In 35 day-old mouse, both of testis and epididymis were luminated and eaithdymal epithelium was differentiated into principal cells and clear cells. Spermatozoa were not transfered into epididymis yet. However, in 80 day-old mouse, both of festis and epididymis were fully differentiated and spermatozoa were transfered into epididymis. In electrophoretic paftem of proteins in epididymal fluid, a total of 28 kinds of proteins were identified, which were different from those of their sera. 12 kinds out of these proteins were epididymal specific protein(ESP) detected in epididymal fluid only, and the other 16 kinds(TEP) were also detected in testicular fluid. The proteins in epididymal fluid changed during sexual maturation and 3 kinds of the proteins changed quantitatively according to epididymal regions in adult. It may be concluded from the above results that the component and composition of the proteins in epididymal fluid changed by the influx of testicular fluid including spermatozoa into epididymis and regulation of the protein synthesis, secretion and/or absorption by the epididymal epithelium. Therefore it is strongly suggested that ESP and TEP in epididymal fluid play somehow significant roles on the maturation of epididymal spermatozoa.

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.
