Serum creatine phosphokinase(CPK) levels were measured serially in 20 adults with closed tibial shaft fractures, CPK activity increased significantly after fracture(p < 0.01). High energy and delayed healing fractures had significantly higher levels of CPK than low energy and normally healing fractures, respectively. Thus, CPK determinations could be used to assess the severity of trauma and possible prognosis of the healing in tibial shaft fractures.

We illustrate serial HRCT findings over a 16-month period in a 35-year-old woman who had ingested paraquat. Initial areas of ground-glass opacity changed into areas of multiple air cysts on follow up scan obtained five months after ingestion. A further follow-up scan obtained 16 months after ingestion showed improvement, with increased lung volume and normalized lung architecture.

BACKGROUND: Thromboembolism is the major complication in patients with the insertion of cardiac prosthetic valves. The purpose of this study is evaluate the risk factors about the formation of left atrial thrombi after cardiac valve replacement. METHOD: Transesophageal(TEE) and transthoracic echocardiography(TTE) were done to evaluate postoperative cardiac condition in 98 patients with cardiac prosthetic valves from Jan. 1991 to Oct 1991. Several clinical and echocardiographic parameters were analyzied to evaluate the relationship with the formation of left atrial thrombi. RESULT: In univariate analysis, important factors related to the formation of left atrial thrombi are type of operation (p=0.027), postoperative left ventricular function(p=0.003), preoperative(p=0.037) and postoperative systolic ventricular size(p=0.024). However, in multivariate analysis postoperative left ventricular size(p=0.017), presence of previous thrombi(p=0.014), preoperative left atrial size(p=0.014) and postoperative left atrial size(p=0.014) are significant factors. CONCLUSION: Patients with high risk and low risk for the formation of left atrial thrombi after valve replacement can be identified by readily available clinical and echocardiographic variables.

BACKGROUND AND OBJECTIVES: Protein kinase C (PKC) is known to be related with development of various cells. In the heart, each isoform reacts differentially against agonists and the reaction changes during development. In this study, the roles of PKC isoforms (alpha, beta, gamma, delta, epsilon, zeta) were investigated through the localization of mRNA expression in the developing rat heart with in situ hybridization histochemistry. MATERIALS AND METHOD: The mRNA expression pattern of PKC isoforms (alpha, beta, gamma, delta, epsilon, zeta) was investigated with in situ hybridization histochemistry in developing and adult rat hearts. Whole body parasagittal sections were used for embryonal day 14 (E14), E16, E18 and heart sections were used for just born (P0), postnatal day 7 (P7), P14, P21 and adult rat. RESULTS: The expression of PKC alpha was found from E14, peaked at P7, and gradually decreased to adult level. The expression of PKC beta was observed from P14, peaked at P21, and decreased to adult level. The expression of PKC delta in the heart was observed from E14, peaked at P0, and abruptly disappeared at P14. The expression of PKC epsilon was observed from E14, peaked at P0, after that gradually decreased and disappeared at adult rat heart. The expression of PKC gamma and zeta was not found from any stage of developing rat heart. CONCLUSION: From these results, it is suspected that each PKC isoform may be differentially related with development of heart. The strong expression of PKC alpha, delta, epsilon around perinatal period, rapidly developing stage, suggests that PKC alpha, delta, epsilon may be related with rapid development of rat heart. And the late postnatal expression of PKC beta suggests that PKC beta may be related with maturation of rat heart.

BACKGROUND: To evaluate the efficacy of transesophageal echocardiography(TEE) to detect left atrial thrombi(LAT) and to investigate the clinical and echocardiography parameters which related with LAT. METHOD: We performed TEE and TTE simultaneously to 98 consecutive patients who had native mital valve disease or mital prosthesis as usual method. We examined the presence and location of LAT and spontaneous contrast(SC) in TEE and measured left atrial dimension(LAD), ejection fraction(EF), mital valve area(MVA) in TTE. Cardiac rhythm, history of anticoagulation and systemic embolization were also reviewed. We compared such parameters in LAT positive/negative groups and SC positive/negative groups. RESULTS: 1) In TEE, we detected 26 cases of LAT, among them seventeen cases : left atrial appendage(LAA) thrombi, 3 cases : combined LA and LAA thrombi, 6 cases : LA thrombi. In TTE, six cases showed LAT but we couldn't detect LAA thrombi. The difference between two methods was statistically significant(p<0.05). 2) LAT positive group showed larger LAD, lower EF, and higher prevalence of AF, systemic embolization, and LAT than negative groups(p<0.01). 3) SC positive group showed larger LAD, lower EF, higher prevalence of AF, systemic embolization LAT than SC negative groups(p<0.05). 4) In multiple discriminant analysis, the history of systemic embolization was most important factor which can suspect LAT(Wilk's Lambda:0.77152. p<0.0001). SC, EF, presence of AF, LAD, anticoagulation therapy. MVR were also statistically valuable factors in order. The hit ratio of this analysis was 86.84%. CONCLUSION: We can suggest that TEE is very useful method to detect LAT than TTE, and the spontaneous contrast was very important factor which can suggest LAT and systemic embolization in mitral valve disease.
