(1) Antral G cells increase in states of achlorhydria in man and animals provided atrophic antral gastritis is absent.
(2) An experimental model was established in the ewe allowing one to predict with accuracy an antral follicle that coincidentally would either undergo ovulation (6-8 mm diameter) or atresia (3-4 mm diameter) following synchronization of luteal regression and the onset of the gonadotropin surge.
(3) Treatment for 5 days with doses greater than 3 micrograms resulted in a significant increase in the total number of growing follicles and the development of antral follicles.
(4) Gastrin-34-LI in antral extracts could be converted to gastrin-17-LI by trypsin in all species.
(5) There were significant direct correlations between antral area and G cell density, between peak acid output and G cell population, and between basal plasma gastrin and G cell density (but not population).
(6) A novel stimulant of gastric acid secretion was extracted and purified from the non-antral gastric mucosa of the canine stomach and some of its biological properties were examined.
(7) Studies in cattle assessing changes in number and size of antral follicles, concentrations of estradiol, androgens and progesterone in serum and follicular fluid, and numbers of gonadotropin receptors per follicle during repetitive estrous cycles and postpartum anestrus are reviewed.
(8) Somatostatin concentrations were higher in antral than fundic tissues (p < 0.05) and remained constant during the postnatal period.
(9) Gastritis occurred in 137 of 163 body specimens (84%) and in 126 of 131 antral specimens (96%).
(10) Equivalent neutralising doses of magnesium hydroxide (pH 9-4) did not increase serum gastrin and gastric acid output above basal levels, whereas antral acidification with 20 ml 0-1 N HCl resulted in a slight decrease in serum gastrin.
(11) Control gilts given saline had ovaries containing antral follicles (4 to 6 mm in diameter).
(12) The antral peptides of both species were identified.
(13) The study using the urease test on mucous biopsies from the antral gastric part and from the duodenum of patients with chronic opisthorchiasis with endoscopic evidence of antral gastritis and gastroduodenitis, and from noninvaded patients with gastritis and duodenitis, some of them with the gastric or duodenal ulcers showed that the test was positive.
(14) Infection with this organism is strongly associated with type B antral gastritis and with peptic ulcer disease.
(15) The first growing follicles appeared in fetal ovaries around Day 180 and consisted mainly of primary and secondary follicles; few antral follicles were present before Day 220 of gestation.
(16) Gastric antral vascular ectasia ('water melon stomach') is a poorly documented cause of occult upper gastrointestinal blood loss.
(17) Antral mucosal diaphragm is uncommon, and presents with manifestations of obstruction to the pyloric outlet.
(18) All five rhesus monkeys that received the strain isolated from rhesus monkeys became H. pylori positive by day 14 and remained positive through day 56 Antral inflammation developed in all monkeys.
(19) After exclusion of subjects with gastritis there remained 67 females and 68 males with morphologically completely normal antral and corpus mucosa.
(20) Following unilateral ovariectomy in the rat, the remaining ovary undergoes rapid compensatory changes including an increase in the number of antral follicles (follicular activation) and an increase in ovarian weight (compensatory ovarian hypertrophy).
