    Notes: Abstract A 66-year-old woman was diagnosed as having lupoid hepatitis due to the presence of hypergammaglobulinemia, lupus erythematosus cells, and positivity for antinuclear, anti-DNA, and anti-smooth muscle antibodies. None of the serum hepatitis B markers were positive. Symptomatic relief was obtained by prednisolone administration. Five years after the diagnosis of lupoid hepatitis, hepatocellular carcinoma (HCC) was detected by ultrasonography and computed tomography, after which hepatectomy was performed. Although transcatheter arterial embolization was done on two occasions and repeat hepatectomy was performed twice for recurrent HCC, her liver function remained good with the prednisolone treatment. Antibody for hepatitis C virus has been negative since our first check in 1992. As of this writing, the patient has been alive and well 6 years and 2 months after the first hepatectomy. There have been no previous reports of 6-year survival after hepatectomy for HCC associated with lupoid hepatitis.

    Notes: Abstract Dissecting aneurysms of the hepatic artery are extremely rare. We report herein the case of a 51-year-old man with massive hepatic metastases from rectal carcinoma, who was found incidentally to have a left hepatic artery aneurysm by a preoperative angiography. After replacing the left hepatic artery with a 2-cm segment of long saphenous vein, an extended right lobectomy with partial resection of the left lateral segment for multiple metastases was successfully performed. To prevent thrombus formation at the anastomosis, the Pringle maneuver was not used during dissection of the hepatic parenchyma. Histological examination of the resected specimen showed a dissecting aneurysm of the left hepatic artery, but there were no findings to suggest the etiology of this disease. The patient is currently alive 13 months after his operation without any evidence of further recurrence of the carcinoma. To the best our knowledge, 12 case reports of this anomaly have been documented, but only one of these describes a successful operation. The clinical features and etiology of the hepatic artery aneurysm that develops independent of other vascular diseases are discussed following this case report.

    Notes: Abstract Hepatic angiomyolipoma is a rare tumor composed of spindle-shaped and epithelioid smooth muscle cells, adipose tissue, and proliferating blood vessels. We report the first documented case of this tumor developing in a patient with ulcerative colitis. A solitary tumor (7.5×7.5×7cm) was detected in the left lateral segment of the liver and a left hepatic lobectomy was performed. The diagnosis of angiomyolipoma was confirmed by a pathological examination. We also review the literature on previously reported cases of hepatic angiomyolipoma.

    Notes: Abstract When subjected to salt stress or drought, some vascular plants such as barley respond with an increased accumulation of the osmoprotectant glycine betaine (betaine), being the last step of betaine synthesis catalyzed by betaine aldehyde dehydrogenase (BADH). We report here cloning and characterization of BADH cDNA from barley, a monocot, and the expression pattern of a BADH transcript. An open reading frame of 1515 bp encoded a protein which showed high homology to BADH enzymes present in other plants (spinach and sugar-beet) and in Escherichia coli. Transgenic tobacco plants harboring the clone expressed high levels of both BADH protein and its enzymatic activity. Northern blot analyses indicated that BADH mRNA levels increased almost 8-fold and 2-fold, respectively, in leaves and roots of barley plants grown in high-salt conditions, and that these levels decreased upon release of the stress, whereas they did not decrease under continuous salt stress. BADH transcripts also accumulate in response to water stress or drought, indicating a common response of the plant to osmotic changes that affect its water status. The addition of abscisic acid (ABA) to plants during growth also increased the levels of BADH transcripts dramatically, although the response was delayed when compared to that found for salt-stressed plants. Removal of plant roots before transferring the plants to high-salt conditions reduced only slightly the accumulation of BADH transcripts in the leaves.

    Notes: Abstract Expression of rice seed storage-protein genes is dramatically regulated over a short period of seed maturation. To characterize the expression mechanism of the rice seed storage protein genes, their expression of major storage protein genes (16 kDa albumin, 13 kDa prolamin and type II glutelin) were compared by RNA blot analysis. Their coordinate expression suggests that the transcriptional regulatory machinery is shared among the glutelin, prolamin and albumin-genes. We isolated two novel genomic genes for prolamins (PG5a and PG5b) and obtained the promoter region of the glutelin gene by PCR. The 5′-flanking regions of these three rice seed storage protein genes were found to contain some similar conserved sequences. Nuclear extract partially purified from maturing rice seeds was used for the gel shift assay of the 5′ region of the RA gene. We identified two DNA sequences of RA gene which were recognized by independent DNA-binding proteins. The complexes of these DNA sequences and DNA-binding proteins were inhibited by the fragments containing the 5′ regions of the prolamin and glutelin genes, suggesting that these three genes share transcription factors.

    Notes: Abstract The Arabidopsis FAD7 gene encodes a chloroplast ω-3 fatty acid desaturase that catalyzes the desaturation of lipid-linked dienoic fatty acids (18:2 and 16:2). An 825 bp FAD7 promoter fragment upstream from the transcriptional start point contained several short sequences which were homologous to the cis-elements (box II, G-box, etc.) conserved in many light-responsive genes. We introduced the FAD7 promoter fused to the β-glucuronidase (GUS) or the luciferase (LUC) reporter gene into tobacco plants. The −825 promoter sequence conferred tissue-specific and light-responsive expression to both these reporter genes in transgenic tobacco, indicating that these expressions of the FAD7 gene were regulated mainly at the transcriptional level. Histochemical GUS staining showed that the activity of the FAD7 promoter is restricted to the tissues with chloroplast-containing cells although the staining was noticeably absent in the chloroplast-containing cells associated with vascular systems. The 5′ deletion experiments of the promoter revealed that the −362/ −166 region, containing two putative box II sequences, was responsible for the tissue-specific and light-responsive expression of the FAD7 gene.

    Notes: Abstract A cDNA of tobacco BY-2 cells corresponding to an mRNA species which was rapidly induced by methyl jasmonate (MeJA) in the presence of cycloheximide (CHX) was found to encode ornithine decarboxylase (ODC). Another cDNA from a MeJA-inducible mRNA encoded S-adenosylmethionine synthase (SAMS). Although these enzymes could be involved in the biosynthesis of polyamines, the level of putrescine, a reaction product of ODC, increased slowly and while the levels of spermidine and spermine did not change following treatment of cells with MeJA. However, N-methylputrescine, which is a precursor of pyrrolidine ring of nicotine, started to increase shortly after MeJA-treatment of cells and the production of nicotine occured thereafter. The levels of mRNA for arginine decarboxylase (ADC), an alternative enzyme for putrescine synthesis, and that for S-adenosylmethionine decarboxylase (SAMDC), required for polyamine synthesis, were not affected by MeJA. In addition to mRNAs for ODC and SAMS, mRNA for putrescine N-methyltransferase (PMT) was also induced by MeJA. Unlike the MeJA-induction of ODC mRNA, MeJA-induction of SAMS and PMT mRNAs were blocked by CHX. The level of ODC mRNA declined after 1 to 4 h following MeJA treatment, while the levels of mRNAs for SAMS and PMT continued to increase. Auxin significantly reduced the MeJA-inducible accumulation of mRNAs for ODC, SAMS and PMT. These results indicate that MeJA sequentially induces expression of a series of genes involved in nicotine biosynthesis by multiple regulatory mechanisms.p〉

    Notes: Abstract Summary. The purpose of this study was to examine the effect of diltiazem on cardiac dysfunction and the change in cardiac gene expression after myocardial infarction in rats. On the first day after myocardial infarction, rats were randomly assigned to a diltiazem treatment (Dil, n = 7) or an untreated group (MI, n = 8). We then performed Doppler-echocardiographic examinations on the rats and measured their hemodynamics at 4 weeks after myocardial infarction. Following these measurements, their cardiac mRNA was analyzed. Diltiazem decreased the mean aortic pressure and heart rate. Left ventricular end-diastolic pressure (LVEDP) and central venous pressure (CVP) increased to 18 ± 2 mmHg and 5 ± 1 mmHg (P 〈 0.01). Diltiazem reduced LVEDP to 14 ± 1 mmHg (P 〈 0.05), but it did not change CVP. The weight of the right ventricle in MI was significantly larger than in the control rats (control, n = 7, 0.46 ± 0.02 g/kg vs. MI, 0.81 ± 0.06 g/kg; P 〈 0.01). The left ventricular end-diastolic dimension (LVDd) in MI increased to 8.8 ± 0.3 mm (P 〈 0.01, control, 6.1 ± 0.3 mm). Diltiazem prevented an increase in the weight of the right ventricle (0.69 ± 0.03 g/kg, P 〈 0.05) and LVDd (7.7 ±6 0.2 mm, P 〈 0.05 to MI). The rats within MI showed systolic dysfunction, defined by a decreased ejection fraction (control, 67 ± 2% vs. MI, 36 ± 3%, P 〈 0.01), and diastolic dysfunction, defined by the E-wave deceleration rate (control, 13.4 ± 1.6 m/s2 vs. MI, 30.4 ± 3.4 m/s2 P 〈 0.01). Diltiazem significantly prevented systolic and diastolic dysfunction. The increases in β-MHC, ANP, and collagen type I and III mRNAs in the noninfarcted left ventricle and right ventricle were significantly suppressed by treatment with diltiazem. α-Skeletal actin increased in MI, and α-skeletal actin was more increased with Dil. In conclusion, diltiazem prevents cardiac dysfunction and morphological change due to left ventricular remodeling after experimental myocardial infarction.

    Notes: Abstract The optimal treatment for recurrent lesions after hepatectomy for colorectal liver metastases is controversial. We report the outcome of aggressive surgery for recurrent disease after the initial hepatectomy and the influence on quality of life of such treatment. Forty-five (70%) of the 64 surviving patients developed recurrence after the initial hepatectomy for liver metastases. The determinants of hepatic recurrence were the distribution and the number of liver metastases. Twenty-eight (62%) of patients with recurrence underwent resection. A second hepatectomy was performed in 20 patients, and a third hepatectomy was done in 5 patients. Ten patients with pulmonary metastasis underwent partial lung resection on 14 occasions, while resection of brain metastases was performed in 3 patients on 5 occasions. There were no operative deaths after resection of recurrent disease. The morbidity rate was 28% after repeat hepatectomy, 21% after pulmonary resection, and 0% after resection of brain metastasis. The Karnofsky performance status (PS) after the last surgery was not significantly different from that after the initial hepatectomy. The 3- and 5-year survival rates after the second hepatectomy were 54% and 14%, respectively. The 3-and 5-year survival rates of the patients undergoing resection of extrahepatic recurrence were both 17%. The survival rate after resection of recurrent disease (n=28) was significantly better than that of patients (n=17) with unresectable recurrence (P 〈 0.05). For the 66 patients with colorectal liver metastases, the 5-year survival rate after initial hepatectomy was 50%. The distribution and the number of liver metastases and the presence of extrahepatic disease, as single factors, significantly affected prognosis after the initial hepatectomy. Multivariate analysis revealed that only the presence of extrahepatic metastasis and a disease-free interval of less than 6 months were independent predictors of survival after the initial and second hepatectomy, respectively. It is concluded that aggressive surgery is an effective strategy for selected patients with recurrence after initial hepatectomy. Careful selection of candidates for repeat surgery will yield increased clinical benefit, including long-term survival.
