Peptones

Derived proteins or mixtures of cleavage products produced by the partial hydrolysis of a native protein either by an acid or by an enzyme. Peptones are readily soluble in water, and are not precipitable by heat, by alkalis, or by saturation with ammonium sulfate. (Dorland, 28th ed)

1.	Duodenal Ulcer (Curling's Ulcer) 07/01/1982 - "Isosmotic liquid peptone meals adjusted to pH 7, 3, and 1.5 were instilled on separate days into the stomachs of 8 duodenal ulcer patients and 7 healthy controls. " 01/01/1979 - "Eleven duodenal ulcer patients were stimulated by a 5% peptone meal. " 10/01/1993 - "Briefly, peptone-stimulated acid output was measured in 15 min periods over 3 h after the injection of drugs in three trials, one with five duodenal ulcer patients, two of them with 8 healthy volunteers each. " 07/01/1991 - "Fasting and peptone meal-stimulated gastrin release at pH 2.5 and pH 5.5 as well as integrated 24-hour plasma gastrin concentrations were significantly higher in the seropositive group, even when subjects with a history of duodenal ulcer were excluded. " 02/01/1980 - " conclude that after peptone test meals, gastric acid secretion in duodenal ulcer patients was abnormally sensitive to stimulation by endogenously released gastrin."
2.	Ulcer 01/01/1986 - "We are investigating the role of anaerobes in the pathogenesis of tropical ulcer and have used Hungate tubes with pre-reduced peptone yeast broth and agar as a transportation system. " 07/01/1982 - "However, after all three tests meals, mean DAL was significantly greater in duodenal ulcer than in normal subjects in both hours of the test, and VPP was significantly greater in ulcer than in normal subjects in the first 40 min. In both groups, following peptone meals of pH 7 and 3, the volume of gastric contents delivered through the pylorus decreased as the amount of free hydrogen ions entering the duodenum increased, but a given load of acid was less effective in slowing emptying duodenal ulcer patients than in controls. "
3.	Shock 10/02/1965 - "Further studies on the problem of the mechanism of peptone shock]." 07/03/1965 - "Studies on the problematic nature of the mechanism of peptone shock]." 01/01/1975 - "The effects of peptone shock on changes in the arterial blood pressure, respiration and urine excretion induced by bladder distension were investigated in 8 anaesthetized female dogs. " 01/01/1975 - "The effect of peptone shock on oliguric-hypertensive bladder reflex." 04/01/1968 - "[The role of the nervous system in the development and outcome of peptone and allergic shock]."
4.	Cholera 11/21/2017 - "This study evaluated the new cholera rapid detection method that relies on Crystal VC dipsticks after enrichment with alkaline peptone water (APW) against the culture method for monitoring the progress of cholera outbreaks in rural setting. " 01/01/2018 - "RDT and bacterial culture were performed on site using fresh stools collected from cholera suspected cases, and from stools enriched in alkaline peptone water. " 11/21/2017 - "Alkaline peptone water enrichment with a dipstick test to quickly detect and monitor cholera outbreaks." 09/01/2011 - "In light of the need for rapid diagnosis of cholera and to prevent spread of outbreaks, we have developed and evaluated a direct one-step lateral flow biosensor for the simultaneous detection of both V. cholerae O1 and O139 serogroups using alkaline peptone water culture. " 10/01/2004 - "A total of 237 feces samples were used to asses the performance of two tests for the rapid detection of Vibrio cholerae 01: the Pathogen Detection Kit (PDK, Intelligent Monitoring Systems, Gainesville, Florida, USA) and Cholera-SMART (New Horizons Diagnostics Corp., Columbia, Maryland, USA), both when applied directly (direct SMART and direct PDK) and when applied to specimens cultured in broth-enriched medium for 6 hours (SMART-6 and CPK-6) and for 18 hours (SMART-18 and PDK-18) at 37 degrees C in alkaline peptone water. "
5.	Inflammation (Inflammations) 06/03/1991 - "Blood PMN from normal rats and from peptone-treated rats showed no significant difference in their response to ZAS indicating that priming of their activity by the induction of long term (8 day) inflammation was not a feature of these experiments. " 06/03/1991 - "PMN are obtained at greater than 90% purity and fractionate at a peak density of 1.0919 g/ml. The method is suitable for isolating PMN when the circulating PMN count is low (less than 20%) as in normal rats and when the count is high (greater than 30%), as a result of inducing inflammation in the subcutaneous air pouch of rats by the intra-pouch injection of peptone. " 04/01/1977 - "Peritoneal macrophages of albino mice with aceptic inflammation of the abdominal cavity caused by intraperitoneal administration of 2 ml of sterile meat-peptone broth were used in the experiments. " 07/17/1907 - "Products of proteolytic digestion, namely, peptone and albumose, absent in the exuded fluid during the first day or two days of inflammation, are present after three days and are found in less quantity at a later period. " 07/01/1976 - "Inbred DA rats bearing a syngeneic 7,12-dimethylbenz[a]anthracene-induced neoplasm had an early impairment of chronic inflammation as measured by the numbers of monocytes elicited in a 3-day peritoneal exudative response to a sterile peptone injection.
