OBJECTIVETo explore the biological effects of infrasound on the polygonal cells in adrenal cortex zona fasciculation in mice.
METHODSThe biological effects of infrasound on the activities of 3beta hydroxysteroid dehydrogenase (3-betaHSDH) and acid phosphatase(ACP) of the polygonal cells in adrenal cortex zona fasciculate were observed when exposure to 8 and 16 Hz infrasound at 80, 90, 100, 110, 120 and 130 dB for 1 day, 7 days and 14 days or 14 days after the exposure.
RESULTSWhen exposure to 8 Hz infrasound, the enzyme activities of 3-betaHSDH increase as the sound pressure levels increase. Only when the sound pressure levels reach 130 dB, the enzyme activities began to decrease exceptionally. When exposure to 16 Hz, 80 dB infrasound, no significant difference between the treatment and control group in the activities of 3-betaHSDH could be observed, but the injury of the polygonal cells had appeared. When exposure to 16 Hz, 100 dB infrasound, the activities of 3-betaHSDH started to increase. The cell injury still existed. When exposed to 16 Hz, 120 dB infrasound, the local tissue damage represented. Fourteen days after the mice exposure to 8 Hz, 90 dB and 130 dB infrasound for 14 days continuously, the local tissue injury of the adrenal cortex zona fasciculation began to recover at certain extent, but the higher the exposure sound pressure level, the poorer the tissue recovery.
CONCLUSIONThe biological effects of infrasound on the polygonal cells in adrenal cortex zona fasciculation response to the frequency of the infrasound are found at certain action strength range, but this characteristic usually is covered by the severe tissue injury. When exposure to infrasound is stopped for a period of time, the local tissue injury of the adrenal cortex zona fasciculation could recovers at certain extent, but the higher the exposure sound pressure level, the more poorer the tissue recovery.

Adreno-hepatic fusion is rare condition defined as adhesion of the liver and right adrenal cortex with close intermingling of the respective parenchyme. It is suggested to be an aging phenomenon, because its incidence is much higher in older age group. Clinically it may pose a problem of operability of the organ involved. We report a case of incidentally found adreno-hepatic fusion in a 49 year old female patient with adenocarcinoma of the sigmoid colon. The segementectomy of VIII segement of the liver was done due to a 6 4 cm sized metastatic nodule of adenocarcioma. Pathological examination of the liver revealed an ovoid shaped, 1 0.5 cm sized adrenal cortical tissue. It was subcapsularly located and about 1cm apart from the metastatic adenocarcinoma with an intervening normal hepatic tissue. The adrenal tissue was mainly composed of zona fasciculata without medullary tissue. In the interphase, the adrenal tissue and liver tissue were admixed closely and partially septated by thin fibrous tissue. There was no inflammatory response to the heterotropically located adrenal tissue and there was no symptom related to the adrenal gland.

The adrenal gland is an important endocrine organ of human body. CYP11B1 gene was specifically expressed in the zona fasciculata in adrenal cortex. In order to better study the function of genes specifically expressed in the zona fasciculata in adrenal cortex, the mice with Cre recombinase specifically expressed in the zona fasciculata in adrenal cortex were constructed. It was then confirmed that CYP11B1 was specifically expressed in adrenal glands. Then, using CRISPR/Cas9 technique, CYP11B1-2A-GfpCre recombinant vector was constructed and subsequently injected into the fertilized eggs of mice. It was confirmed that the Cre gene was mainly expressed in the zona fasciculata in adrenal cortex of CYP11B1Cre mice by using mTmG and LacZ staining. The CYP11B1Cre mice were then mated with cystathionine γ-lyase (CTH) mice, thereby generating CTH/CYP11B1Cre mice. It was also confirmed that CTH gene in the zona fasciculata in adrenal cortex was specifically knocked out in these mice. These results suggest that transgenic mice with specific Cre recombinase expression in the zona fasciculata in adrenal cortex were constructed successfully. This animal model can be a powerful tool for the study of the function of genes expressed in the zona fasciculata in adrenal cortex.

Preadipocyte factor-1 (Pref-1) is expressed in the neuroendocrine organs such as the pituitary gland, the adrenal gland, the pancreas, the testis, etc. Vitamin D3 up-regulated protein 1(VDUP1) gene is known to be a novel member of early response genes as an oxidative stress mediator. The aim of the present study was to investigate whether Pref-1 and VDUP1 is involved in stress response in the adrenal gland following chronic immobilization stress. In situ hybridization for Pref-1 and VDUP1 genes (Pref-1 and VDUP1) was performed in the rat adrenal glands following immobilization stress, 2 hr once daily for 7 days. In situ hybridization analysis revealed that Pref-1 expression was up-regulated in rat adrenal medulla following chronic immobilization stress. However, Pref-1 was down-regulated in the zona glomerulosa of the adrenal cortex following chronic immobilization stress. VDUP1 expression was up-regulated in the zona glomerulosa and the adrenal medulla following chronic immobilization stress. These results show that Pref-1 and VDUP1 may be novel genes responding to chronic immobilization stress in adrenal gland.
