Background: In Japan, neonates have typically been bathed in a bathtub immediately after birth because bathing is a custom for cleansing impurities. However, dry technique has been introduced into many institutions since 2000. There is little scientific evidence on the ben- efit or harmfulness of either method to neonatal skin, and consequently, opinion remains split on which method is superior. Objective: The purpose of the present study was to determine whether bathing or the dry technique of cleaning is better in maintaining skin health in the early neonatal period. Methods: Transepidermal water loss (TEWL) and skin pH, considered an index of skin bar- rier function, were measured in each group. Tumor necrosis factor (TNF)-alpha and inter- leukin (IL)-6, which are inf lammatory cytokines released by keratinocytes, were measured by skin blotting. Results: TEWL and skin pH of neonates were lower with the dry technique than with bath- ing. The expression level of IL-6 and TNF-α in chest skin of neonates was higher with bath- ing than with the dry technique. Conclusion: These results suggest that the dry technique may maintain skin health better than bathing in the early neonatal period.

Casein hydrolysate, prepared with Aspergillus oryzaeprotease, contains angiotensin I-converting enzyme in-hibitory peptides, such as Val-Pro-Pro and Ile-Pro-Pro. We conducted a randomized, double-blind, placebo-controlled studyto evaluate the effect of casein hydrolysate on the blood pressure of 144 subjects with high-normal blood pressure (n . 104)and mild hypertension (n . 40). Subjects were randomly assigned to two groups for a 12-week intake period. In the test group,both systolic (SBP) and diastolic (DBP) blood pressure decreased significantly compared with the placebo group: SBP/DBPsignificantly decreased from 138.2. 6.5/84.4. 5.3 mm Hg at week 0 to 132.3. 7.3 (P. .001)/81.2. 4.8 mm Hg (P..001) at week 12. In the stratified analysis, the test product showed an antihypertensive effect in both the subject group withhigh-normal blood pressure and that with mild hypertension. No side effect was observed in any subjects in this study. Theseresults demonstrate that the casein hydrolysate, prepared with A. oryzaeprotease, produced a significant reduction in bloodpressure in a population of subjects with high-normal blood pressure or mild hypertension without an adverse event.

The purpose of this study was to determine if salivary chromogranin a secretion in dogs exhibits a circadian rhythm. Saliva sampling was performed during three different sessions occurring in three nonconsecutive 24-h periods. Sixteen healthy adult beagle dogs (8 males and 8 females) were moved to a sampling room and housed individually in cages. Saliva samples were obtained every 4 h from 12:00 p.m. to 12:00 p.m. the following day. In the interest of habituation, saliva was obtained hourly from each dog 3 h before the experiment was started. Salivary chromogranin A concentrations were measured using an enzyme-linked immunosorbent assay. No circadian rhythm was detected for salivary chromogranin A secretion, and no differences in salivary chromogranin A concentrations measured every 4 h were demonstrated during the 24-h cycle in dogs.

An epidemiological study on canine intestinal parasites was undertaken to evaluate changes in the prevalence among private household dogs from the Hachinohe region of Aomori prefecture, Japan, in 1997, 2002 and 2007, using the formalin-ethyl acetate sedimentation technique. The risk of zoonotic transmission from household dogs to humans was also discussed. All intestinal parasites detected in the present study (Giardia intestinalis, Isospora spp., Toxocara canis, Ancylostoma caninum, Trichuris vulpis and Strongyloides stercoralis) showed no changes in prevalence over the past 10 years based on analysis considering canine epidemiological profiles. In particular, prevalence of Giardia intestinalis in dogs under 1 year old, derived from pet shops/breeding kennels and kept indoors was unchanged, remaining at a high level of >15.0% at each time point. Toxocara canis also showed no changes in the group of dogs under 1 year old, bred by private owners and kept outdoors, and the prevalence was >10.0% every year. The present results indicate that the prevalence of Giardia intestinalis and other intestinal parasites in private household dogs has not always decreased, and the potential for direct parasitic zoonotic transmission from dogs to humans may be relatively high level, than from the environment (indoors and outdoors). We recommend careful surveillance of intestinal parasites and aggressive use of anthelminthic in private household dogs under considering the epidemiological factors.
