Eine weitere Beobachtung zur Frage des Läusestreuens     

Fritz Steiniger 《Journal of pest science》1948,21(2):27-28

Zusammenfassung Neben dem in einer früheren Darstellung behandelten Herunterfallen von L?usen, die sich beim Umherlaufen auf der Kleidungs-oberfl?che gegenseitig mit den Beinen verkrallen, kommt als Ursache für das L?usestreuen auch die K?ltestarre der L?use in Frage, die bei Temperaturen in der N?he von 0° eintritt. Die Beobachtung an verlausten Kleidungsstücken bei −6°C zeigte, da? bei Windst?rke 5–6 L?use im Zustand der K?ltestarre von dem Luftzug, bereits von den Stoffunterlagen abgerissen werden k?nnen.  相似文献

Rabbit lactate dehydrogenase isozymes: effect of pH on activity     

P J Fritz 《Science (New York, N.Y.)》1967,156(771):82-83

The ability of lactate dehydrogenase isozyme five from rabbit skeletal muscle to catalyze pyruvate reduction is extremely sensitive to changes of pH within the range of 6.2 to 7.8.The activity of lactate dehydrogenase isozyme one from rabbit heart is virtually unaffected by changes of pH within the same range. Isozyme five is activated by low concentrations of oxalacetate and inhibited by higher concentrations, but other substrates of the citric acid cycle have no effect.  相似文献   

Diclazuril preventive therapy of gamma interferon knockout mice fed Sarcocystis neurona sporocysts     

Dubey JP  Fritz D  Lindsay DS  Shen SK  Kwok OC  Thompson KC 《Veterinary parasitology》2001,94(4):257-264

Gamma interferon knockout (KO) mice (n=74) were fed a lethal dose of approximately 1000 sporocysts of the SN15-OP isolate of Sarcocystis neurona. Groups of mice were given pelleted rodent feed containing 50ppm of diclazuril at different times before and after feeding sporocysts. All mice were examined at necropsy and their tissues were examined immunohistochemically for S. neurona infection. Twenty mice were fed sporocysts and given diclazuril starting 5 days before feeding sporocysts and continuing 30-39 days post-infection (p.i.). One mouse died of causes unrelated to S. neurona with no demonstrable parasites; the remaining 19 mice remained clinically normal and S. neurona organisms were not found in their tissues. Sarcocystis neurona organisms were not demonstrable by bioassay of the brains of these 19 mice in uninfected KO mice. Sarcocystis neurona organisms were not found in tissues of five mice treated with diclazuril, starting 7 days after feeding sporocysts and continuing up to 39 days p.i. Therapy was less efficient when diclazuril was given 10 days p.i. Sarcocystis neurona organisms were found in two of 19 mice treated with diclazuril starting 10 days after feeding sporocysts, in two of five mice starting therapy 12 days p.i., and in 10 of 10 mice when treatment was delayed until 15 days p.i. All 15 mice fed S. neurona, but not given diclazuril, developed neural sarcocystosis and were euthanized 22-30 days after feeding sporocysts. Six mice not fed S. neurona, but given diclazuril for 44 days, remained clinically normal. Results indicate that diclazuril can kill the early stages of S. neurona.  相似文献   

Change in intraocular pressure during maturation in Labrador Retriever dogs     

Mughannam AJ  Cook CS  Fritz CL 《Veterinary ophthalmology》2004,7(2):87-89

Objective To measure intraocular pressure (IOP) in a group of dogs as puppies and young adults to determine if there is any change during maturation. Animals studied Thirty‐two healthy Labrador Retriever dogs. Procedures Intraocular pressure was measured using a Tonopen XL initially at approximately 6 weeks of age (T1), then again approximately 1 year later (T2). Exact ages were known based on whelp date. Results The dogs had marginally higher IOP OU at T2 (mean = 14.9 mmHg) compared to T1 (mean = 13.4 mmHg). However, the difference was not statistically significant. No differences were seen based on sex and litter. Intraocular pressure OD was statistically greater than OS at T1 but not at T2. Conclusions Normal values for intraocular pressure are the same in puppies and adults. The results of this study do not support the previously suggested theory that younger dogs have sustained increased IOP as a requirement to drive growth of the globe. However, it does not rule out the possibility that a dynamic relationship between intraocular pressure and expansion of the globe may exist.  相似文献
