Fruit are normally kept in a pouch of cold storage room in winter. In this work, a mathematical model that is emulating the fruit respiration in the pouch of the storage has been established. The calculated result is compared to the actual measured gaseous composition change of pear in the packaging pouch LDPE film incorporated with silver coated ceramic powder. The presented model, that is combining polysaccharide digestion kinetics in pear, Fickian diffusion for permeation of the film and sigmoidal adsorption equilibrium between the film and gases, predicts the respiration of the pear in the packing film fairly well.

A successful treatment of infants and children with congenital heart defects depends upon several factors: diagnosis must be accurate, the operative technique, including techniques of perfusion and myocardial preservation, must be suited to the needs of patients and intensive cares, including accurate anesthesia, must be applied through all stages of investigation and treatment, i.e. before, during and after the operation. Recently we performed a open heart surgery successfully for a six-years old girl who had suffered from frequent upper respiratory tract infection and mild to moderate exertional dyspnea with congenital heart defects (ventricular septal defect, Kirklin type II, with patent foramen ovale). The operation and postoperative course were very smooth. And now we report this with review of literatures.

<P><B>Background</B></P> <P>The primary objective was to calculate and to apply the numeric value of the distance from the pectoralis major tendon insertion to the superior aspect of the humeral head (PMTD) without any radiation exposure or equipment through basic data such as age, sex, height, and weight of Asian populations.</P> <P><B>Methods</B></P> <P>We analyzed shoulder magnetic resonance images of 260 patients (107 men and 153 women; average age, 59.8 years). The superior border of the pectoralis major was identified on the transverse section and cross-referenced with the coronal section. Measurements were made inferiorly from the corresponding transverse section to the top of the humeral head superiorly in coronal view. Correlation analysis was performed between variables including the patient's age, sex, height, weight, and body mass index and the PMTD by multiple linear regression analysis.</P> <P><B>Results</B></P> <P>The mean PMTD was 52 mm, with an average of 55 mm for men and 49 mm for women. Sex and height were significantly correlated with PMTD. The PMTD increased to a consistent level proportionally to height, and the difference in PMTD between men and women was 3.45 mm. An equation to estimate PMTD using these findings is as follows: PMTD (in mm) = 23 + (height [cm] × 0.17) + 3.45 (the last number is added for men). This equation had a prediction error of 0.3 mm.</P> <P><B>Conclusion</B></P> <P>Our study demonstrated that PMTD is a useful and reliable reference for optimal humeral height during hemiarthroplasty for proximal humerus fractures in Asian populations.</P>

POEMS (Polyneuropathy, Organomegaly, Endocrinopathy, M-component, and Skin changes) syndrome, also called as Takatsuki syndrome or Crow-Fukase syndrome, is a multisystemic syndrome that encompasses progressive peripheral neuropathy, papilledema, increased CSF protein, hepatomegaly, splenomegaly, lymphadenopathy, diabetes mellitus, gynecomastia and impotence, amenorrhea, hypothyroidism, osteosclerotic bone lesion, plasma cell dyscrasia, and thickening, hyperpigmentation and hypertrichosis of the skin. Recently, we experienced a 39-year-old male who had been suffered from generalized weakness, both shoulder pain, leg pain, weakness of the lower extremities, impotence, hoarseness, dysphagia, and aspiration of food. He had various signs such as peripheral neuropathy, papilledema, hepatomegaly, splenomegaly, primary gonadal failure, hyperprolactinemia, hypothyroidism, hypoparathyroidism, osteosclerotic bone lesions, and plasmacytoma by bone biopsy, erythematous papules of the skin proven to be proliferating endotheliosis by biopsy, leg edema, ascites and pericardial effusion. He also had hyperkalemia, decreased fractional excretion of potassium and hyporeninemic hypoaldosteronism.

Background : In the skin, it is often difficult to differentiate lymphomas from reactive lymphoid lesions by light microscopic examination. Ohjective: Our purpose was to determine whether immunologic data obtained from mutine-processed specimens could be used to further objective morphologic interpretations. Methods : We conducted an immunohistochcmical staining in 44 cases of benign and malignant cutaneous lymphoproliferative lesions using nine antibodies, including anti-CD3, UCHL1, MT1, MT2, L26, MB2, BerH2, 123C3, and MIB1. Results: 1. Immunophenotyping with anti-CD3, UCHL1, MT1, L26, and MB2 was useful for the diagnosis of T cell or B cell lymphoma. However, these antibodies showed a lack of specificity for neoplastic cells, 2. Antibody to CD56, 123C3 showed positivity in 4 cases of angiocentric lymphoma, but negativity in 8 cases showing angiocentric lymphoma-like pathology. 3. Antibody to CD30, BerH2 showed positivity in all 6 cases of CD30 positive large cell lymphoma, but negativity in 6 cases showing diffuse lymphoma-like pathology. 4. Antibody to Ki-67, MIB1 showed positivity in more than 30% of infiltrating cells in 6 cases of angiocentric lymphoma, 4 cases of diffuse B cell lymphoma, and in more than 60% of infiltrating cells in 6 cases of CD30 positive large cell lymphoma. Conclusion : These observations suggest that immunostaining may provide useful adjunctive information in distinguishing benign from malignant cutaneous lymphoproliferations in paraffin sections.

The syndrome of ectopic production of ACTH by non-pituitary neoplasm occurs with various types of tumors. ACTH-producing thymic carcinoid tumor is rare and has not been reported in Korea. We have experienced a 36-year-old male patient with ACTH-producing thymic carcinoid tumor, presenting symptoms of generalized weakness and weight gain. Clinical presentation, radiologic and hormonal evaluation, and pathologic examination were compatible with ACTH- producing thymic carcinoid tumor. The immunohistochemical staining of the thymic carcinoid tumor showed positivity for ACTH. Primary and metastatic tumor and both adrenal glands were resected. Radiation therapy and chemotherapy were performed. The prognosis of this patient is thought to be poor. (J Korean Soc Endocrinol 12:647-654, 1997)
