What's the difference between acinus and racemose?
Acinus
Definition:
(n.) One of the small grains or drupelets which make up some kinds of fruit, as the blackberry, raspberry, etc.
(n.) A grapestone.
(n.) One of the granular masses which constitute a racemose or compound gland, as the pancreas; also, one of the saccular recesses in the lobules of a racemose gland.
Example Sentences:

(8) The development of a new method to isolate hepatocytes originating from the proximal or distal half of the liver acinus enabled the measurement of total cytochrome P-450 content and of cytochromes P-450b and P-450e mRNAs in these hepatocytes.
(9) These results indicated that there is modulation of the expression of the cytochromes P-450b and P-450e genes within the hepatic acinus.
(10) The alveoli in each acinus were reduced in size and, in some cases, number--although their stage of differentiation was normal for age--pointing to a disturbance of growth during later fetal life also.
(11) Monoclonal antibodies against PR and ER were mainly located in the epithelium of the excretory duct and granular convoluted tubule, but not in the acinus.
(12) Clofibrate induced the activities of carnitine acetyltransferase (90-fold), carnitine palmitoyltransferase (3-fold) and NADP-linked malic enzyme (3-fold) to the same level in periportal as in perivenous hepatocytes, suggesting that these enzymes were induced uniformly throughout the liver acinus.
(13) We have optimized a cerium-diaminobenzidine-based method for histochemical analysis of glucose-6-phosphatase (G6Pase) activity and have determined quantitative data on the zonal distribution pattern in the liver acinus of fasted male rats.
(14) Hepatocytes in the perivenous zone immediately adjacent to the hepatic venules in the liver acinus are positive for GS.
(15) The preacinar cells were occasionally observed at the site between acinus and intercalated duct.
(16) Thus, in the intact pancreas, acinar cells intercommunicate extensively within each acinus under resting conditions and reduce their coupling during stimulation.
(17) cells, but the microsomal GST and cytosolic GR were found to be evenly distributed in the acinus.
(18) Numerous micromorphological differences and resemblances between rabbit and cat were found: Acinus 1.
(19) In the mammalian liver the distribution of ammonia-detoxifying enzymes, glutamine synthetase (GS) and carbamoylphosphate synthase I (ammonia) (CPS-I), is mutually exclusive in that these enzymes are expressed in two distinct populations of hepatocytes that are zonally demarcated in the liver acinus.
(20) During their voyage, they traverse the three acinus zones, and since in each they produce different enzymes, each zone represents a differentiation state of the advancing cell.
Racemose
Definition:
(a.) Resembling a raceme; growing in the form of a raceme; as, (Bot.) racemose berries or flowers; (Anat.) the racemose glands, in which the ducts are branched and clustered like a raceme.
Example Sentences:
(1) Five patients had parenchymal cysts and presented with epilepsy; three had the racemose form and presented with hydrocephalus.
(2) We have reported a case of a racemose cyst of the fourth ventricle.
(3) Congenital anastomoses can be of the racemose hemangioma type, with severe malformation of the retinal vessels, ocular complications, and neurologic manifestations, or as simple A-V shunts with visual impairment but limited tendency to show other ocular or neurologic involvement.
(4) Microscopic examination showed the racemosal type of cysticercus but no scolex was found.
(5) The coenuri closely resembled examples of racemose cysticerci described in the literature and the present results are discussed with reference to human cases of asexually proliferating larval cestode infections.
(6) Clinical progression requires surgery, especially for racemose angiectasia.
(7) A thin subependymal or subpial rim of high signal intensity around the intraventricular and one of the racemose cysts was consistent with tissue reaction and aided diagnosis.
(8) Bronchoscopic examination revealed a polypoid tumor of the left B4 bronchus, which was resected and diagnosed as racemose hemangioma.
(9) Five patients with either capillary-cavernous hemangiomas or arteriovenous racemose hemangiomas were selected to illustrate the angiographic features of vascular malformations of the face as well as problems in angiographic evaluation and therapeutic techniques.
(10) A histological examination of a piece of the reddish, racemose tumor removed during microlaryngoscopy revealed only some slight nonspecific inflammatory changes.
(11) As well, they demonstrate that repeated cerebrospinal fluid analysis may result in diagnostic confirmation of intracerebral cysticercosis of the racemose type.

(15) Fluid in apparently live cysticerci and in racemose cysts had MR signal properties closely paralleling CSF.
(16) Ultrathin serial sectioning and labeling with tannic acid have demonstrated that most plasmalemmal vesicles of rat vascular endothelial cells are not free, but rather are conjoined in three dimensions to form racemose invaginations from the cell surfaces.
