Clinical application of insect-based diet in canine allergic dermatitis

The objective of this study was to evaluate the beneficial effects of the short-term application of insect-based diet in canine allergic dermatitis. Total 19 atopic dogs with concurrent cutaneous adverse food reactions were enrolled and classified into 3 groups. The treatment group (n = 7) was fed insect-based diet, the positive control group (n = 6) was fed salmon-based diet, and the negative control group (n = 6) was fed commercial or homemade diet for 12 weeks. The degree of skin lesions was evaluated based on canine atopic dermatitis extent and severity index (CADESI-4). Additionally, transepidermal water loss (TEWL) and pruritus visual analog scale were evaluated. All indices were evaluated every 4 weeks after the initial administration of hypoallergenic diets. In the treatment group, significant decrease in the CADESI-4 score was observed at 8 weeks compared to the baseline score (p = 0.031). There were significant differences in the CADESI-4 score between the groups at 8 weeks (p = 0.008), 12 weeks (p = 0.012), and TEWL at 12 weeks (p = 0.022). This preliminary result demonstrates the potential hypoallergenicity of an insect-based diet through features that diminish cutaneous lesions and skin barrier dysfunction.

Clinical trial of oral administration of Bifidobacterium longum in dogs with atopic dermatitis

This study assessed the effects of probiotics in canine atopic dermatitis (AD). We enrolled 11 client-owned dogs with AD and randomly allocated them to two groups. The probiotics group (n = 7) was prescribed with Bifidobacterium longum while the control group (n = 4) received a placebo powder once a day for 12 weeks. In both groups, the degree of skin lesions was evaluated based on the Canine Atopic Dermatitis Extent and Severity Index (CADESI)-4. We also measured the transepidermal water loss (TEWL). We assessed pruritus severity using the pruritus visual analog scale (PVAS). Alteration of consumed drug doses was converted into medication scores. All the evaluation indices were surveyed every 4 weeks. In the probiotics group, there was a significant decrease in the CADESI-4 score at 4, 8, and 12 weeks compared to that of the baseline score (p < 0.05). There was no significant difference in TEWL, PVAS, and medication score at each time point and between groups. Although these results showed that Bifidobacterium longum did not reduce pruritus, TEWL, and the dosage of drugs for canine AD, it was effective in improving skin lesions, therefore, probiotics could be considered in canine AD with severe skin symptoms.

Reserpine treatment activates AMP activated protein kinase (AMPK)

Reserpine is a well-known medicine for the treatment of hypertension, however the role of reserpine in cell signaling is not fully understood. Here, we report that reserpine treatment induces the phosphorylation of AMP activated protein kinase (AMPK) at threonine 172 (T172) in PC12 cells. Phosphorylation of AMPK T172 is regulated by upstream signaling molecules, and the increase of phospho-T172 indicates that AMPK is activated. When we examined the FOXO3a dependent transcription by using the FHRE-Luc reporter assay, reserpine treatment repressed the FHRE-Luc reporter activity in a dose dependent manner. Finally, we showed that reserpine treatment induced the phosphorylation of AMPK as well as cell death in MCF-7 cells. These results suggest that AMPK is a potential cellular target of reserpine.

Plasma Atrial Natriuretic Peptide Concentrations of the Pulmonary artery, Aorta and Veins in Children with Caridac Disease

To study the site of release and factors affecting the release of the atrial natriuretic peptide(ANP) in the pediatric patients, we measured the plasma ANP concentrations in 23 normal healthy children, 19 patients with congestive heat failure and 16 patients with cardiac disease undergoing diagnostic cardiac catheterization. The following results were obtained. 1) The plasma ANP concentrations of the vein(226.3(74.9pg/ml)in patients with congestive heart failure were significantly higher than those(p<0.01)of the mormal healthy children(13.4 (7.9pg/ml)and those(43.3 40(.7pg/ml)in patients undergoing cardiac catheterization. The plasma ANP concentrations of the femoral vein in patients undergoing cardiac catheterization were also significantly higher than that of the peripheral vein in the normal healthy children(p<0.01). 2) The plasma ANP concentrations of the pulmonary artery(110.9( 80.7pg/ml)were 2 to 3 times higher than that of the femoral vein(43.3( 40.3pg/ml, p<0.01). However there were no significant differences of the plasma ANP concentrations between pulmonary artery and aorta(65.4 (36.1pg/ml),and between aorta and femoral vein. 3) There was a significant correlations of the plasma ANP concentrations vetween pulmonary artery and femoral vein, and pulmonary artery and aorta, but no correlation of those between femoral vein and aorta. 4) The plasma ANP concentrations of the vein were over 3 times more higher in cases of left atrial area over 20 cm2/M2 measured by 2-dimensional echocardiography(213.2 (292.9pg/ml)than those in cases of left atrial area under 20(65.0 66.9pg/ml, p<0.05). The plasma ANP concentrations of the vein were over 3 times more highger in cases of left atrial area over 20 cm2/M2(88.6(19.1pg/ml) than those in cases of left atrial area under 14(57.1 (39.5pg/ml,p<0.05), and in cases of the sum of both atrial mean pressure over 11mmHg(189.5( 42.8pg/ml) than those in cases of the sum under 11(79.3 (52.3pg/ml, p<0.01). The plasma ANP cocentrations of the aorta were significantly higher in cases of left atrial area over 14 cm2/M2(88.6 (19.1pg/ml)than those in cases of left atrial area under 14(57.1 (39.5pg/ml;p 0.05), in cases of the sum of both atrial area over 25cm2/M2(93.9 (21.7pg/ml)those in cases of the sum under 25(46.6 (33.8pg/ml, p<0.01), in cases of sum of mean atrial pressure over 11 mmHg(90.5 (30.3pg/ml)than those in cases of under 11(53.8( 24.6pg/ml, p<0.05),in cases of the sum of both atrial wall stress over 190 mmHg.cm2/M2(101.4 (23.5pg/ml) than those in cases of the sumunder 190(57.5 (26.4pg/ml, p<0.01), and also in cases of pulmonary artery mean pressure over 20mmHg(83.3( 18.2pg/ml) than those in cases o pulmonary artery under 20(47.8( 39.8pg/ml, p<0.05). In conclusion, the plasma ANP concentrations of the pulmonary artery were significantly higher than those of the frmoral vein and the aorta, which indicater that the ANP is predominantly secreted via coronary sinus into the right atrium. The plasma ANP concentrations of the peripheral and femoral vein, the pulmonary artery and the aorta, especially that of the aorta, correlated well with the atrial pressure, the area and the wall stress. This suggests that the arterial blood may be the most appropriate sample for measurement of the ANP.

A Case of Oligodendroglioma in the Septum Pellucidum

The authors report a case of oligodendroglioma in the septum pellucidum. A 22-year-old male presented with symptoms of headache and decreased visual acuity. Simple skull series showed calcified density near the midline. Brain C-T scan revealed huge calcified mass involving right lateral ventricle, 3rd ventricle and obstructive hydrocephalus. The authors diagnosed oligodendroglioma in operative findings and pathologic examination.

We reported congential and traumatic odontoid process fracture which were successfully treated by transoral fusion. Operative preparation, technique and postoperative management are described by in detail.

Late Hemorrhagic Disease of Infancy due to Vitamin K Dependent Factor Deficiency

A clinical study was done on 9 children with 10 episodes, who were admitted to our pediatric ward under the diagnosis of late hemorrhagic disease of infancy due to vitamin K dependent factor deficiency. Study period was past 2 years, from September 1979 to May 1981. The following results were obtained. This disorder occurred most frequently during early infancy, with male predominence, male female ratio being 4:1. And breast feeding was noted in 6, with history of previous medication for URI in 7. GIT was the most common site of bleeding occurring in 9 cases, followed by CNS in 3, skin in 1 and nose in 1. Anemia, probably due to blood loss, was seen in 8 cases, and dehydration, oral thrush, fever, irritability, mental change and convulsion were seen in small number of cases. Initial laboratory findings showed prolonged PT and PTT with normal platelet count in all cases. After vitamin K therapy, PT and PTT became normal in majority of cases. Prompt response to vitamin K therapy within 24 hours was noted in 6, prolonged response over 3 days in 2, and one patient showed recurrence at 2(1/2) months after complete recovery from first episode.
