In the treatment of flexor tendon injury of the hand, re-rupture after primary tendon repair is one of complications which occurs occasionally and so impose burden on both the patient and the surgeon. Authors experienced twelve cases of re-rupture after primary flexor tendon repair of 274 patients from Mar. 1989 to Mar.1996. The incidence of re-rupture after primary flexor tendon repair was 4.4% in author's series. One case happened with slip down injury, and in six cases re-rupture occurred during physical therapy with snapping click sound. However in five cases, the patients conldnt recognize any related causes. In majority of cases, re-ruptures were identified between three and five weeks after primary repair by the surgeon and the patient, so it could be suggested that the attention should be paid for the high possiblity of re-rupture during this period. Operative findings were the resorption and friability of repaired end with insecure suture fixation in two cases, rupture of suture material in four cases and loosening of the knot in six cases. From this study, the authors suggest the importance of knot, and recommend to make more than four knots on suture tie with attention to the tie direction, and advise careful physical therapy according to each patients' different situation. In the treatment of re-rupture, end-to-end re-anastomosis was available in seven cases (59%). In five cases (41%), tendon graft was needed. The clinical result of the re-rupture cases was evaluated by the Stickland evaluation method, and it was satisfactory in 67% of the patients who had the complication of re-rupture.

INTRODUCTION: The phenomenon related to sign & symptom management for end of life of the patients is of interest to researchers in nursing society today. This study was conducted to clarify and to conceptualize the factors of sign & symptom management in end of life care though nurses' perceptions on this phenomena. METHODS: The qualitative study method was used to explore the experienced nurses' perceptions related to sign & symptom management in end of life care. It included a field study carried out in South Korea using in-depth interviews with 30 experienced nurses from three nursing home facilities. RESULTS: This study identified the following categories related to end of life care with sub-categories for each category: (1) nurses' modes in identifying the signs related to patients' end of life, (2) nurses' perceived directions on patients' end of life care, (3) nurses' perceived strategies in end of life care and (4) nurses' perceived barriers in end of life care. CONCLUSION: Through this study, characteristics of the way nurses' provide for patients' end of life care are identified, along with how nursing decisions are made to manage the sign & symptom indicating patients' end of life.

Lymphangioleiomyomatosis(LAM) is a rare disease of unknown etiology that occurs mainly in woman in her reproductive age. We recently experienced two cases of bilateral diffuse cystic lesion of the lung on chest X-ray and HRCT. The first case, a 26-year-old female, who had been diagnosed with tuberous sclerosis be the presence of clinical manifestation such as mental retardation, bilateral renal angiomyolipoma, adenoma sebaceum and generalized seizure, was admitted due to recently developed hemoptysis. Chest PA showed diffuse ground-glass opacity with radiolucent cystic lesions of various sizes on both lung fields. HRCT showed innumerable small cystic lesions with suspicious diffuse ground-glass opacity on both lung fields. The second case, a 30-year-old female was admitted due to dyspnea and spewing of blood-tinged sputum for 2 weeks, shortly after delivery. Chest PA showed diffuse reticular and ground-glass opacities on both lung field. HRCT showed multiple well-difined and relatively uniform size air cysts with a uniform wall thickness on entire both lung fields, with small amount of right pleural effusion. By thoracoscopic lung biopsy she was diagnosed with pulmonary lymphangioleiomyomatosis. We report these cases with a brief review of the literatures.

Tofacitinib, which is used to treat rheumatoid arthritis (RA), is primarily metabolized by the hepatic cytochrome P450 (CYP) enzymes, CYP3A1/2 and CYP2C11. Acetaminophen (APAP), which is frequently used for pain relief in patients with RA, can induce acute liver injury (ALI) when taken in excess, profoundly affecting drug metabolism. Resveratrol (RVT) is a polyphenolic compound with hepatoprotective properties. This study investigated the protective effects of RVT against APAP-induced ALI in rats, and explored its influence on the pharmacokinetics of tofacitinib. In ALI rats, both intravenous and oral administration of tofacitinib resulted in a significant (207% and 181%) increase in the area under the plasma concentration-time curve (AUC), primarily driven by a substantial reduction (66.1%) in non-renal clearance (CLNR) compared to that in control (CON) rats. Notably, RVT administration in ALI rats provided effective liver protection, partially restoring liver function, as evidenced by normalized glutamate oxaloacetate transaminase levels and the pharmacokinetic parameters, AUC and CLNR, closer to those observed in untreated CON rats (117% and 81.9%, respectively). These findings highlight the importance of considering the potential interactions between RVT or polyphenol-rich natural products and medications in patients with ALI in clinical practice.

Tofacitinib, a Janus kinase (JAK) inhibitor used to treat rheumatoid arthritis, is metabolized through hepatic cytochrome P450 (CYP), specifically CYP3A1/2 and CYP2C11. Prolonged administration of rheumatoid arthritis medications is generally associated with an increased risk of renal toxicity. Loganin (LGN), an iridoid glycoside, has hepatorenal regenerative properties. This study investigates the potential of LGN to mitigate acute kidney injury (AKI) and its effects on the pharmacokinetics of tofacitinib in rats with cisplatin-induced AKI. Both intravenous and oral administration of tofacitinib to AKI rats significantly increased the area under the plasma concentration-time curve from time 0 to infinity (AUC) compared with control (CON) rats, an increase attributed to the decelerated non-renal clearance (CL NR) and renal clearance (CL R) of tofacitinib. Administration of LGN to AKI rats, however, protected kidneys from severe impairment, restoring the pharmacokinetic parameters (AUC, CL NR, and CL R) of tofacitinib to those observed in untreated CON rats, with partial recovery of kidney function, as evidenced by an increase in creatinine clearance.Possible interactions between drugs and natural components should be considered, especially when co-administering both a drug and a natural extract containing LGN or iridoid glycosides to patients with kidney injury.

This preliminary study was intended to clarify the effect of intraoperative fluid therapy on Acid-Base balance of the use of Hartmann's solution and 5% Dextrose solution. The arterial carbon dioxide partial pressure and oxygen partial pressure and pH are basic indices of the adequacy of ventilation in anesthetized patients, respiratory care and intensive care. In order to achieve this goal, the data collections were done at the Department of Anesthesia in Hanil Hospital from Mar., 1980 to Aug., 1980. The samplings, 20 cases, were included A.S.A. class I and II. We used 1,500 to 1,800cc/2hrs. of Hartmann's solution and 1,000cc/2hrs, of 5% Dextrose solution each 10 patients through the operative period. Observations were made for the followings; pH, PaCO2HCO-3. From the results of this study, there were no significant relationship between the use of 5% Dextrose solution and Hartmann's solution on Acid-Base balance during the intraoperative period.
