This study was carried out to investigate the morphological changes in the exocrine and endocrine glands of rat pancreas treated with endotoxin. Thirty-five male Sprague-Dawley rats, maintained on a stock diet, weight 200.0 gm. average. were divided into two experimental groups. Group 1. Control group. Five rats. Intraperitoneal infections of 0.3 ml normal saline only. Group 2. Endotoxin-treated group. Thirty rats. 7.6 mg of endotoxin per kg. of body weight was administered intraperitoneally. Each of 5 experimental animal was sacrificed 30 minutes, 1, 2, 4, 6 and 8 hours after endotoxin treatment, followed by examinations of histochemical, light and electron microscopy of both transmission and scanning modes. The results were as follows: A. Light microscopic findings: A mild interstitial edema and hyperemia were noted 1-hour after endotoxin treatment. Cytoplasmic vacuolization at 2-hour level(2-hours after endotoxin administration), diminished staining quality of both endocrine and exocrine cells at 6-hour level. B. Electron microscopic examination: a. Transmission electron microscopy. The acinar cells of pancreas showed a mildly increased pre-lysosome at 30-minute level. At 1-hour level, appearance of secondary lysosome was noted in addition to the findings of mitochondrial swelling and decreased cristae; disarray and vacuolization of the RER; vacuolar change of Golgi apparatus. At 6-hour level, post-lysosomes. The changes in the endocrine glands were similar to the findings of exocrine glands just described with time lag of 1 to 2 hours. The endothelial cells of capillaries show swelling and pinocytotic vesicle formation, protrusion of the cytoplasmic processes into the capillary lumen and increased heterochromatin at 1-hour level. These findings became more prominent as time lapses. The lumen of the endothelium tends to be narrowed, filled with fibrin and other blood cell components which later terminated with occasional complete occlusion by the formation of thrombi. b. Histochemical study: Primary lysosomes of the control group revealed a strong reaction of the acid phosphatase whereas the endotoxin treated group with less reactivity limited in the peripheral zones of the lysosomes. Secondary lysosomes with partial reactions. However, the pre-lysosomes and post-lysosomes failed to demonstrate any acid phosphatase activity at all. c. Scanning electron microscopy. The endothelial cells of the capillaries, arterioles and venules demonstrated increased microvillous activity, broad bled formation, cytoplasmic protrusion into the luminal spaces and microthrombi formation at 1-hour level. Six-hour level onward there noted a junctional disruption and partial detachment from the subendothelium of the wall. It can be concluded, therefore: When the endotoxin enters the blood stream, it elicits endothelial injury followed by both exudation with resultant edema of the surrounding tissue and concomitant vascular occlusions due to thrombosis. This vascular occlusion, in turn, causes ischemic degenerative change of the cells of exocrine and endocrine glands of the pancreas which are followed by digestions of degradational materials from the injured cells through the lysosomal phagocytic system. Besides the above pathogenetic pathway, one can not rule out the possibility of the direct effects of the endotoxin to the cells of exocrine and endocrine cells of the pancreas also so rendered.

There are a number of published reports aimed at clarifying the effect of hormonal contracept -ives upon the quantity and quality of breast milk during postpartum and lactation periods. As to the volume of milk produced by breast feeding mothers, many authors seem to have agreed on a decrease as an established pattern in the periods following regular administration of oral contraceptives containing estrogen in varying dosage. The quality of milk following administration of hormonal contraceptives, however, remsins a controversial issue. Korea's experience in oral contraceptive is rather a brief one, but use of Eugynon has been widespread and frequent since this hormonal contraceptive was introduced into the national program in 1967. The authors have reviewed the potential significance of data concerning regular use of an oral contraceptive as affecting lactation, and have sought to clarify the interrelationship between the administration of Eugynon and quantity and quality of breast milk from mothers contracepting. with Eugynon in different periods following confinement. A total of 85 women, who were at different periods following deliveries, have been divided into, two groups, one comprising 28 women regularly taking oral pills and the other (57 women) not resorting to hormonal contraceptives if they were contracepting at all. 1. Milk Volume. In view of the possible influence of suckling on the amount of milk produced, efforts were made in this study to standardize the technique by extracting breastmilk by applying manual pressures on one side of the maw-nae, While the nipple on the other side was being sucked by the mother's own baby. The effetct of an exogenic ovarian hormone on the quantity as well as quality of breastmilk is generally understood to be inapparent until the drug is administered to women whose milk secreting function has been normalized. ") In the present study, it was observed that the decrease in the ammount of milk obtained from mothers in the periods following the 4th cycle of oral contraceptives or thereafter has turned out to be statistically insignificant. This result conforms i.u the findings by Tubari and others. It is assumed that it takes at lest 2 to 3 cycles of use before mammary glands are functionally adjusted to the use of exogenic hormonal contraceptives. 2. Specific Gravity and Composition of Milk There was no noticeable change in the protein and chloride content following continuous administration of ore.l contraceptives, while meaningful changes were observed in fat (increase) and calcium (decrease up to the 5th cycle use) contents. Also, there was a rather significant decrease in the specific gravity in the period following administration of the first cycle of the oral contraceptive. The findings from the present study partially conforms the results published by Ramadan and others, who reported that little change was noticed in the contents of total solids. ash, chlorides and lactose in the breast milk of women who had taken 4 cycles of ovosiston, although in our study lactose was not measured. Ramaden, however, reported that fat content did increase in the same milk, as in our study. A definitive conclusion, however, could not be made unless measures are taken to rule out the physiological changes of the maternal body affecting the composition of milks.

PURPOSE: The purpose of the study was to explore and describe hospice palliative nurses' experience of caring for terminal cancer patients. METHODS: Eleven hospice palliative nurses participated in the study. Data were collected through individual in-depth unstructured interviews with participants from November, 2012 to October, 2013. Theoretical sampling was used to the point of theoretical saturation. Data were analyzed using Corbin and Strauss' 'Grounded Theory Method.' RESULTS: From open coding, 25 sub-categories and 12 categories were identified. Analysis revealed that the core category was 'becoming stepping-stones between life and death enduring burdens', consisting of three phases: the phase of withdrawal, the phase of exertion, and the phase of maturity. Through this process, participants utilized various action/interactional strategies such as 'maintaining a distance', 'sharing intimate daily life', 'being a mediator for a peaceful death', 'grieving and remembering'. The consequences of these strategies were a transcendental perspective towards life and ambivalent feelings toward hospice nursing. CONCLUSION: In-depth understanding of the hospice palliative nurses' experience of caring for terminal cancer patients will guide nurse managers and policy makers to promote effective nursing strategies to better support hospice palliative nurses.

Forty-five modified arthroscopic transglenoid suture capsulorrhaphy were performed between January 1989 and May 1995 with minimum follow-up of one year among sixty-four recurrent anterior shoulder instability in Chungnam National University Hostital. The average age at operation were 25 year and average time interval from injury to surgery were 12 month. we classify the Bankart lesion into 4 type according to the extent of capsulolabral complex detatchment, associated glenoid rim fracture, type II SLAP lesion and absence of glenoid labrum. Type Ia have a separation of labrum and inferior glenohumeral ligament from the glenoid rim and scapular neck (classic Bankart lesion) and type IIa have a capsular separation and glenoid rim fracture. Type IIIa have above mentioned type Ia or type IIa with type II SLAP lesion and type IVa have capsular separation without identifiable labral structure. We also subdivided the each type into subgroup b according to coexistence of capsular laxity. We modify the capsular suture technique according to classification. Type Ia, and type IIa were treated with in situ Bankart repair. Type Ib and type IIb were treated with capsular advancement. Type IIIa and 1IIb were treated with Bankart repair and additional fixation of SLAP lesion. Type IVa and IVb were treated with purse string type suture (capsular shift superiorly) with multiple stitches. All patients had various shape of Bankart lesion, so author s proposed classification of the Bankart lesion can be applied to each type. Arthroscopic finding were as follows. Twelve shoulders (27%) have type Ia Bankart lesion and six patient (13%) have type lIa lesion. Type lIIa were observed in eight shoulders (18%) and four patient (9%) were type IVa. The capsular laxity (subgroup b) were found in 15 patient (33%). None of the 45 patients experienced intraoperative complications or infec tion. All patients had full, painless range of motion and had no recurrence except four patient. One is type IIIa Bankart lesion in which associated type II SLAP was not repaired and the other two patients had sport injury and one patient had severe retrauma on 2 years after operation. We conclude that Bankart lesion is the essential lesion of recurrent anterior shoulder instability and were founded in all cases of recurrent anterior shoulder instability, and modified athroscopic transglenoid suture capsulorrhaphy according to arthroscopic classification is safe and effective method with acceptable recurrence rate.
