Pada studi kasus ini kami mendokumentasikan sebuah kasus prolapsus kantung pipi pada seekor hamster mini Campbell (Phodopus campbelli). Hamster mini Campbell datang dengan anamneses adanya sebuah massa di kiri mulut bagian dalam yang tampak menyembul keluar. Berdasarkan pemeriksaan klinis, hamster mengalami prolapsus kantung pipi dengan prognosa yang buruk. Terapi awal yang dilakukan berupa reposisi, akan tetapi terjadi prolaps kembali sehingga dilakukan amputasi pada kantung pipi yang mengalami prolap.

Golden (Mesocricetus auratus) and Siberian (Phodopus sungorus) hamsters are widely used as animal models for seasonal reproduction; butM. auratusshows no developmental delay in short days until after sexual maturity, whereasP. sungorusjuveniles delay development in short days. As the photoperiodic response ofPhodopus campbelliis not well established, litters of the twoPhodopusspecies were gestated and reared under long days (14 h light:10 h darkness) or short days (10 h light:14 h darkness) until 70 days of age. As expected, under short photoperiodP. sungorusshowed reduced body, testes, epididymides, uterus, and ovary weight; antral follicles and corpora lutea were absent and vaginae remained closed. Animals moulted to winter pelage, and low concentrations of each of leptin, testosterone, and prolactin were present in male serum.Phodopus campbellijuveniles also responded to the short photoperiod as measured by reduced body, testes, epididymides, and ovary weight. The summer pelage persisted. However, both sexes ofP. campbellideveloped functional reproduction under 10 h light:14 h darkness. All females had a patent vagina by 10 weeks; ovaries contained antral follicles and corpora lutea, and uteri were not reduced in weight. In males, the concentrations of testosterone, leptin, and prolactin were not reduced by short photoperiod. Developmental patterns in the three species of hamster, therefore, differ and are not predicted by relatedness or latitude of origin. Other ecological traits, such as predictability of summer rainfall, ambient temperature, and differential responses to social cues might be important.

Response To Water

The dwarf hamsters Phodopus campbelli and P. sungorus are found in semi-arid areas of Siberia and northern Mongolia, but habitat and diet differences suggest species differences in water regulatory efficiency. These differences were investigated by examining the effect of moderate water restriction (50% of ad libitum consumption) on solitary dams and on their reproductive success. In response to water restriction, P. sungorus dams lost less body mass than P. campbelli dams, and despite similar litter sizes, P. sungorus produced heavier litters and pups than P. campbelli, indicating that P. sungorus pups were larger. These results suggest that P. sungorus is more tolerant of water restriction than P. campbelli. In a second experiment the possibility that paternal care may mitigate the effects of water restriction was examined by leaving the mated pair together throughout lactation. Pairing reduced mass loss by P. campbelli dams and increased the proportion of large P. campbelli pups at weaning, but had no effect on these measures in P. sungorus, eliminating interspecific differences in responses to water restriction. Results suggest that biparental care may be a facultative response to environmental stress in P. campbelli.
